Looking for reliable Indian Railways data for college/personal project!

I'm actually building a project where I need reliable/correct data of Indian railways, basically about trains, stations, schedules , timings etc. I've looked around the internet and had no success as such , I did find some git hub repos in the way but like they are old and nothing is mentioned where they got their data from.Data from the government was released in 2015 and last updated in 2018 , so there's that.

Found something called Pravah for indian railways, but I need to be registered as a business to use this service,then there is this Rapid API option but obviously it paid once the limit of 50 is reached. India has around 13,000 trains so obviously, can't use it.

Since it is a college/personal project I'm actually trying to keep the resources I use free at least under a justifiable budget.
