<p>Train travel in India is more than just going from one place to another &#8211; it’s a journey rich in both nostalgia, and shared moments. For years, carrying home-cooked food was part of the ritual: comforting and economical meals filled with the warmth of family care. But with evolving preferences for traveling light, many passengers today are turning to more convenient alternatives like ordering on-the-go. Services like Zomato’s <strong>‘Food on Train’</strong>, integrated with IRCTC’s e-catering platform, allow travellers to order meals and have them delivered directly to their seats, redefining dining while traveling.</p>



<p>This blog explores why travellers are increasingly choosing <strong>Zomato’s Food on Train service</strong>, a trusted and convenient solution for enjoying meals during their train journeys.</p>



<h2 class="wp-block-heading"><strong>When home-cooked meals aren’t always feasible</strong></h2>



<p>While home-packed food holds a special place in Indian travel culture, it isn’t always the most practical choice — especially for longer journeys, impromptu trips, or when traveling with kids or elderly family members. Preparing, packing, and carrying food containers along with your luggage can be time-consuming and logistically challenging. The idea of on-the-go restaurant meals, therefore, becomes more appealing.</p>



<p>Zomato’s <strong>Food on</strong> <strong>Train service</strong> offers a convenient solution to help travellers choose food from local legendary restaurants or global brands, all while retaining the comfort of familiar meals.</p>



<h2 class="wp-block-heading"><strong>Get meals from trusted restaurant partners</strong></h2>



<p>Station food and pantry services are integral to the Indian Railways experience but we understand that passengers seek more variety or a chance to explore regional cuisines, new restaurants and more.</p>



<p>For this, Zomato offers access to an array of <strong>FSSAI-certified restaurants </strong>to choose from at almost all major stations. For food delivery accuracy, we track the train status in real-time to ensure the meals received don’t compromise the passengers convenience &amp; timeliness.</p>

5 Common Myths About Ordering Food on Trains Online – Debunked!


<p>Growing up in the bylanes of Mumbai, brothers Mohammed Selia and Faisal Sunesara were drawn to the comforting chaos of their local Jamaat kitchen. Amidst the bubbling pots, aromatic spices, and generous servings, their quiet love for cooking started blooming.</p>



<h2 class="wp-block-heading"><strong>The early days</strong></h2>



<p>Their initial training ground was right at home.<strong><em> “Our fathers and forefathers were in the restaurant industry,”</em></strong> Faisal Sunesara shares. <strong><em>“Watching them work inspired us to start something of our own.”</em></strong></p>



<p>In those early years, they absorbed both the discipline of service and the thrill of experimenting with flavours that clicked with people. While Faisal Sunesara studied commerce and Mohammed Selia pursued science, both felt a familiar pull towards the kitchen.</p>

<p>A brief stint in the UK gave Faisal Sunesara a fresh perspective.<strong><em> “I noticed a stark difference between the baked goods available abroad and what we found at home. That’s what first got me thinking of a way to bring those flavours to Mumbai, at prices people here would find appealing.”</em></strong></p>



<h2 class="wp-block-heading"><strong>The first step</strong></h2>



<p>In 2016, that thought became action when the brothers launched the first Deliure outlet—a dessert spot rooted in warmth and quality. They chose Claire Road for its familiarity and proximity to their family’s other businesses.</p>



<p><strong><em>“From the beginning, we’ve done thorough research before setting up each outlet,”</em></strong> says Faisal Sunesara.</p>



<h2 class="wp-block-heading"><strong>Growing against the odds</strong></h2>



<p>They grew quite slowly in the beginning. Taking a call on pricing was one of the toughest decisions they had to make.</p>



<p>Faisal Sunesara explains, <strong><em>“Because of our product quality, many felt we should price on the higher side. But we stuck to our idea of keeping it reasonable, since we wanted our delicacies to reach households across the city.”</em></strong></p>


<div class="wp-block-image">

<p>As complete newcomers to the bakery business, the brothers also had to compete with well-established brands. He mentions, <strong><em>“People already had favourites. We had to work twice as hard to build a name people could trust.”</em></strong></p>



<p>To create awareness, they turned to online and on-ground campaigns, inviting people to sample their creations and experience the difference firsthand. Faisal Sunesara says, <strong><em>“As we connected with communities in different localities, we found pockets of customers who truly appreciated what we offered.”</em></strong></p>



<h2 class="wp-block-heading"><strong>A platform that enables</strong></h2>



<p>That same year, Deliure onboarded with Zomato. <strong><em>“It was all about accessibility, making it easier to deliver our products to people across the city,”</em></strong> says Mohammed Selia.</p>



<p>Then came a turning point in 2018. With the support of KAM Zaid Zameer, Deliure gained steady traction and soon crossed a hundred monthly orders. That’s when the brothers knew Mumbai had found its sweet spot.</p>



<h2 class="wp-block-heading"><strong>Resilience through COVID</strong></h2>



<p>The pandemic dealt a heavy blow. Two outlets had to be shut. But the Claire Road branch stayed open for a few hours a day, thanks to special permission from local authorities.</p>



<p><strong><em>“I would work in the kitchen myself,” </em></strong>Faisal Sunesara recalls. <strong><em>“People missed their favourite baked goods. We wanted to be there for them, to offer some comfort during those troubled times.”</em></strong></p>



<h2 class="wp-block-heading"><strong>Scaling flavours, expanding dreams</strong></h2>



<p>Despite the hurdles, Deliure grew rapidly between 2018 and 2023—order volumes surged 40x. With the KAM’s guidance, the menu expanded thoughtfully, growing beyond just desserts to include savouries, Mumbai-style chaats, and refreshing beverages.</p>

<p>They combined this with their agility. <strong><em>“We were quick to hop onboard with the latest food trends,” </em></strong>says Mohammed Selia. <strong><em>“To take one instance, we were among the first to launch the kunafa chocolate cake, as soon as the flavour became viral.”</em></strong></p>



<p>Still, expansion didn’t come easy. <strong><em>“We were nervous about opening new outlets,”</em></strong> shares Mohammed Selia. <strong><em>“We feared we’d have to shut down. But we kept pushing. And because of our quality and pricing, we have been able to achieve success with every new outlet that we’ve set up.”</em></strong></p>



<h2 class="wp-block-heading"><strong>Sweet new horizons</strong></h2>



<p>Started as a small store in Mumbai, Deliure has now grown to twelve thriving locations across Mumbai—with more on the horizon.</p>



<p>Mohammed shares that one of their biggest lessons has been the importance of constant innovation. To stay relevant, they go beyond following trends, and aspire to set them too.</p>



<p>He adds, <strong><em>“Our goal is to go far and wide and reach every corner of Mumbai. And for that, we’ll keep giving our best to everything we do.”</em></strong></p>


Sweet roots, big dreams and a whole lot of frosting: The Deliure Story


<h2 class="wp-block-heading"><strong>Introduction</strong></h2>



<p>At Zomato, we develop and deliver fast, necessitating fast feedback loops. However, in a world of hundreds of microservices, testing the end-to-end flow can become time-consuming. To overcome this, we introduced Local Preview. This powerful development tool empowers developers to test their microservices directly on their local machines, eliminating the need to deploy to a shared environment. This tool is essential for accelerating the development process by providing immediate feedback on code changes and fostering better collaboration among developers working on different microservices.</p>



<h2 class="wp-block-heading"><strong>Ideal Development Environment</strong></h2>



<p>An ideal development environment champions Local-First Development, where developers can test their entire code flow locally. It ensures:</p>



<ol class="wp-block-list">
<li>Early Issue Detection &#8211; Testing locally enables developers to identify and resolve issues before deploying to shared environments, reducing the chances of integration failures and deployment delays.</li>



<li>Faster Feedback Loop &#8211; Immediate feedback on code changes speeds up development and debugging, eliminating time wasted waiting for CI/CD pipelines or remote environments.</li>



<li>Easier Code Debugging &#8211; We can leverage code debugging tools to debug code locally with ease, using breakpoints.</li>
</ol>



<h2 class="wp-block-heading"><strong>Problems with the Previous Workflow</strong></h2>



<p>At Zomato, we initiate the development process with coding and conducting initial testing on local machines. But the large number of microservices made it challenging to simulate every case locally. Several services have high dependencies on upstream services that are difficult to run locally. Moreover, local machines have inherent limitations on the number of services they can run simultaneously.</p>



<p>Once confident about the functionality of the code locally, the developers push changes to the remote repository, raise a pull request, and wait for reviews. Once the code is approved and merged, it will be deployed to the staging environment. The staging environment is a copy of the production environment (though not as scaled), with all services running. Only at this stage could we perform a comprehensive end-to-end (E2E) test and validate the changes on the UI.</p>



<p>If a bug was found during testing in the Staging Environment, the entire cycle had to be repeated:</p>


<div class="wp-block-image">
<figure class="aligncenter size-full is-resized"><img data-recalc-dims="1" loading="lazy" decoding="async" width="367" height="281" src="https://i0.wp.com/zomatoblog.com/wp-content/uploads/2025/06/image4.png?resize=367%2C281&#038;ssl=1" alt="" class="wp-image-14623" style="width:430px;height:auto" srcset="https://i0.wp.com/zomatoblog.com/wp-content/uploads/2025/06/image4.png?w=367&amp;ssl=1 367w, https://i0.wp.com/zomatoblog.com/wp-content/uploads/2025/06/image4.png?resize=300%2C230&amp;ssl=1 300w" sizes="auto, (max-width: 367px) 100vw, 367px" /></figure></div>


<p>The time taken for each cycle was significant, as each iteration involved multiple steps and dependencies. Despite its slowness, this workflow helped maintain high code quality and uptime, even while meeting aggressive product deadlines.</p>



<h2 class="wp-block-heading"><strong>Solutions We Explored</strong></h2>



<p><strong>`rsync` local code to remote</strong></p>



<p>Our approach involved using rsync to synchronize the code from the local machine to a dedicated remote instance using our in-house command line tool ( zctl ). rsync copies the code present on the local machine to the remote machine, which is connected to the service mesh. This allows all flows to be tested on the remote machine while maintaining a faster feedback loop. We will deep dive into this in a future blog post.</p>



<p><strong>Introducing Preview Environment</strong></p>



<p>We launched the Preview Environment (which will be discussed in detail in a future blog post). It allows developers to deploy their code to an ephemeral environment that runs in parallel with staging, skipping the PR review process. However, even with the preview environment, the process still required us to push our code to the remote repository and wait for the application to be rebuilt and redeployed before testing could begin. This meant that while iteration time was significantly reduced, there was still substantial room for improvement.</p>


<div class="wp-block-image">
<figure class="aligncenter size-full"><img data-recalc-dims="1" loading="lazy" decoding="async" width="640" height="293" src="https://i0.wp.com/zomatoblog.com/wp-content/uploads/2025/06/image1.png?resize=640%2C293&#038;ssl=1" alt="" class="wp-image-14626" srcset="https://i0.wp.com/zomatoblog.com/wp-content/uploads/2025/06/image1.png?w=788&amp;ssl=1 788w, https://i0.wp.com/zomatoblog.com/wp-content/uploads/2025/06/image1.png?resize=300%2C137&amp;ssl=1 300w, https://i0.wp.com/zomatoblog.com/wp-content/uploads/2025/06/image1.png?resize=768%2C352&amp;ssl=1 768w" sizes="auto, (max-width: 640px) 100vw, 640px" /></figure></div>


<p>To address this bottleneck, we developed Local Preview, which enables faster feedback by allowing developers to test changes locally without the overhead of remote builds and deployments.</p>



<h2 class="wp-block-heading"><strong>Local Preview &#8211; Bringing the Power of Preview to Everyone’s Local Machine</strong></h2>



<p>Local Preview eliminates even more friction by enabling developers to test their microservices locally without deploying them to staging. This tool significantly speeds up the development process by providing immediate feedback on code changes. It is powered by a service deployed in our staging environment, called Local Proxy.</p>



<p>Local Proxy is responsible for routing calls from the staging environment to the local machine. It acts as a proxy between staging and local, using TCP Tunneling. The Local Proxy leverages components such as SSH Daemon and Envoy to manage connections and effectively route requests.</p>



<p><strong>Here’s How it Works</strong></p>



<ol class="wp-block-list">
<li>The local Machine initiates a connection to the Local Proxy service to establish the reverse tunneling. Our zctl tool streamlines this process. It uses SSH to establish a secure TCP reverse tunnel between the local machine and the staging environment. This tunnel allows developers to test their services locally while maintaining a secure connection.</li>



<li>It relies on a unique HTTP header (<em>preview-id</em>) to distinguish requests intended for local services from those meant for standard staging services..To implement this, we are using the <a href="https://kuma.io/docs/2.10.x/policies/traffic-route/" data-type="link" data-id="https://kuma.io/docs/2.10.x/policies/traffic-route/">traffic-route</a> policy of Kuma service mesh.</li>



<li>If a call contains the required <em>preview-id</em>, it is then routed to the Local Proxy.</li>
</ol>



<pre class="wp-block-code"><code>type: TrafficRoute
mesh: dev
name: xyz-service
sources:
  - match:
      kuma.io/service: '*'
destinations:
  - match:
      kuma.io/service: xyz-service
conf:
  destination:
    kuma.io/service: xyz-service
    route_id: default
  http:
    - match:
        headers:
          preview-id:
            regex: .*xyz-service-29160.*
      destination:
        kuma.io/service: xyz-service
        route_id: xyz-service-29160
</code></pre>



<p>4. Local Proxy directs the call to the local machine via an SSH reverse tunnel. Envoy manages the routing of requests to the appropriate local service. It is configured to handle requests based on the <em>preview-id</em>, ensuring that each request reaches the correct destination.</p>


<div class="wp-block-image">

<p>5. Calls from the local service to the upstream microservices are routed to the Delegated Kuma-gateway via an internal VPN. The Kuma-gateway acts as an ingress gateway, routing requests based on headers. Staging datastores can also be connected from the local environment using the same internal VPN.<br>6. Local preview also has built-in failure recovery and monitoring systems. This is achieved by implementing two-way health checks and failure reports sent to both the developer’s machine and a central Grafana dashboard.</p>



<h2 class="wp-block-heading"><strong>Conclusion: Fast Feedback, Smarter Development Cycles</strong></h2>



<p>Local Preview is a huge step in shifting left in our development process, making early testing faster, easier, and closer to the developer. It enables developers to test E2E flow on their local machine, drastically improving the feedback cycles. Since the local machine hosts the server, testing won’t be possible if it goes to sleep or the server is stopped. It&#8217;s best suited for individual testing, but has limitations when used in a collaborative environment. For final testing, it is ideal to deploy the changes to the preview environment, where anyone can test the code by setting the <em>preview-id</em> in the call.</p>



<p>Header Propagation is mandatory in all the services present in the call path. If <em>preview-id</em> header is lost, calls will not be routed to the preview service, as its functionality is dependent on the header.</p>
