Build GTFS for the Hungarian State Railways (Magyar Államvasutak, MÁV).

Usage no npm install needed!

<script type="module">
  import buildMavGtfs from '';



Build GTFS from the Magyar Államvasutak (MÁV, Hungarian State Railways) REST API using the mav JS module. Please ask MÁV for permission before using this module in production.

Please note that the data basis used by the MÁV API allows GTFS data to be generated only 25 days in advance.

Work in progress. This software is not stable yet. See the to-do section.

npm install --save build-mav-gtfs


npm install -g build-mav-gtfs



The script takes a startDate and an endDate JS Date() object (the feed will include the endDate, days will be calculated in Europe/Lisbon timezone) and return a Promise that will resolve in an object containing GTFS object streams:

const generateGTFS = require('build-mav-gtfs')

generateGTFS(new Date("2017-12-01T00:00:00"), new Date("2018-05-31T00:00:00"))
.then((gtfs) => {

The GTFS object contains the following streams:

  • agency
  • stops
  • routes
  • trips
  • stop_times
  • calendar_dates
  • feed_info


build-mav-gtfs start-date end-date directory
build-mav-gtfs 01.12.2017 31.05.2018 ~/cp-gtfs

To do

  • minify/optimize gtfs calendar_dates to calendar

@juliuste will be working on this the next few days.
