This museum has around 100 life size exhibits, an indoor gallery, an auditorium, a toy train for children to take a ride in and a souvenir shop. It took me over 2 hours to cover it. if with children then you might want to skip the uninteresting parts. Better go early in the morning or in the evening. The afternoon sun takes a toll on your enthusiasm to read the write ups.
Personal train saloons belonging to the kings, dynamometer bogies, patiala monorail, viceregal dining car, steam locomotives, number plates, landmarks, 100 year old electrical fittings etc. There is lot's to see. The souvenir shop is nice. You get train replicas, paper weights, calenders. They make for unusual gift items.
Definitely worth a visit when in Delhi!
