National Rail Museum at Chanakyapuri, which was formally inaugurated in February. 1977, is one-of-its-kind museum in Asia, which has an interesting collection of history, heritage, romance, nostalgia, fun, leisure and entertainment, all at one place. Sprawling over 11 acres, it comprises an indoor gallery devoted to the display of various exhibits, models, records, photographs, coat of arms, documents etc. over 100 real size exhibits display the glory of the bygone era. The Museum promises to take the visitors on an exciting journey into the Railway history and heritage and depict their contribution to the industrial and economic progress of the country.  
One major attraction is the majestic Fairy Queen which first rolled out for the erstwhile East Indian Railway in 1855. For the first time after 1908, the Fairy Queen rolled again on Feb. 1st, 1997 from Delhi to Alwar. The steam engine is the oldest working engine in the world. Finding its pride of place in the Guinness Book of World Records and also capturing the National Tourism Award, this prestigious pristine beauty those graces the Rail Museum is steaming once again.
Another interesting piece is the "Sir Leslie Wilson" of the GIPR, which was one of the first electric locos to work in India. It was built in 1928 and was retired in 1974. Apart from an awesome collection of engines you can see the opulence of the carriages used by the Maharajas in their time & the collection of old crockery & cutleries.
The museum is in a big green park so in winter spending an afternoon here is great fun. The museum is closed on Mondays.

An absolute must for rail buffs!! I had a great day out here, despite in being of the warmest days ever in Delhi!! The exhibits are a flashback to the days when steam power stitched together the fabric of the Sub Continent. Mountain Railway Engines to Maharajah's opulent carriages and lots more besides. Even the skull of an elephant who came of the worse for wear after headcharging a locomotive
I've got some pictures somewhere??

There is a tiny rail museum (not too small) at Mysore too. Those who visit this part can walk into. It's just close to the railway station

I spent a whole day at Chanakyapuri (the museum) in December 2001 and enjoyed it immensely. The next day, the Indian parliament was invaded by the terrorists and all hell broke loose.
