Fodor's Expert Review National Rail Museum

This large, mostly outdoor museum is a glimpse into the largest railroad system in the world. The 10-acre grounds are home to 75 authentic locomotives, bogies (railway cars), royal saloon cars, and even a working roundabout (a device that turns rail cars). Parked behind glass is the Fairy Queen; built in 1855, it's the oldest running steam engine in the world. Inside the museum are displays that discuss the history of India's rail system. The museum is good not only for train buffs but also children, who love riding the tiny train that circles the grounds.
