The author Mark Twain - who this carriage is named after - described his trip on the railway in 1896 as "the most enjoyable day I have spent on the earth".
One famous telegram sent from the line to headquarters in Calcutta during Mark Twain's time allegedly said: "Tiger eating station master on front porch. Telegraph instructions."
The views from the train's windows are some of the most spectacular in the world, and if you look closely it is sometimes possible to see Mount Everest in the far distance.
Most drivers of the train - which goes up to 2,286 metres (7,500 feet) say it is one of the most enjoyable jobs in the world, attracting a wide variety of well-known visitors.
One admirer of the train's British engineering was Mother Teresa, who said that she heard God calling her to be a missionary in Calcutta while using the service in 1946.
Drivers today are full of praise for the train's Victorian engineers. The short wheelbase of Darjeeling's "toy train" is now world famous, as is its zigzag method of climbing hills.
In 1999, the UN declared the line a World Heritage Site, declaring it "an outstanding example of an innovative transportation system".
Another well known traveller on the railway was the former BBC India correspondent, Sir Mark Tully, who used it regularly during his school days at Darjeeling in the 1930s.
The railway today is more than just a tourist attraction. It also provides economical transport for workers going to and from Darjeeling.
The Darjeeling Himalayan Railway Society now has more than 800 members in 24 countries. They are determined to ensure the service will carry on rattling for many more anniversaries.
