I implement the information system of railway transportation.
Tell me, is there a possibility on a non-commercial basis to implement some API, in which the selected railway route would be displayed on the map? Suppose I need to get from Chelyabinsk to Yekaterinburg, I enter the data into a form, and the route is displayed next to the map.
Suddenly, who faced. Yandex does not have such a service, I did not find anything in Google.
