This is a must visit if you’re visiting Chennai irrespective of your age. The property is next to the ICF(Integral Coach Factory) in New Avadi Road. It has ample space for parking your 2/4 wheelers. I was there today & witnessed could of school buses & couple of college buses as well. For kids, it was an excursion but for the college students, it was an industrial visit.
They charge ₹50 for adults as an entry & ₹15 for kids (per person). For adults, you’re also entitled for a snack(Samosa) or drink(Tea/Coffee) which is prices at ₹10.
They have massive halls which exhibits their products and the evolution of Indian railways. They also have a Park where kids can play. Water & Toilet facilities are also available.
Do not miss taking the ride on a toy train which is fee of cost. It goes inside a small tunnel as well apart from taking you around the property which will last for 2-3 minutes.
There is also a fully air conditioned movie theatre which shows the video(around 30 minutes) about various aspects of railways including the world’s longest & fastest trains.
They also have a restaurant inside. I did not go there since this visit was a sudden one.
You can spend a good 3-4 hours in this place at a nominal cost. You can find more pics on my Google Local Guides page.
