Sounds like you're a little new to the Indian "shell game" of finding rolling stock.
From past experience, MANY of the Indian contributors, though some are getting much better, tend to be lax when it comes to providing the correct information as to where you find the rolling stock and engine files they are using in the activities. Some don't bother at all in a few of the most recent activities, or use stock from payware sites unknown to us without the link or name of them.
ONE big danger I have to warn you about, especially Indian Rwy locomotives. MANY of them are hidden in the ZIP file with a number of other units, and the download zip name will not always match the engine you want. If the file is listed in our Train-Sim library, your best bet, as one reader has mentioned is doing a search by ENG or WAG name you want on "Indianrailsim.com" this will tell you right away what ZIP file it is in.
Good luck in your searches, as I have been doing it a number of years now with many of the available Indian routes and matching activities....NEVER knew they had so many trains (the site "https://www.trainspnrstatus.com/runningstatus" is excellent for schedules and station codes / information) and many-all of them are huge 18 car plus consists

Happiness is when the AI-trains appear where you want them to
