THE WATER TANK is seen frequently along the route of the railroads and plenty of water must be taken on and carried in the engine tender to make steam which is the power used to drive the big engines.
AN OBSERVATION TRAIN is often made up to follow the great college boat races, where the railroad runs along the river bank. Flat cars are used with seats fixed on them for the spectators.
THE TRAIN FERRY carries entire trains across rivers where there are no bridges. Some of the largest train boats have several tracks and carry a train on each. The boats are tied in slips at the shore so that the tracks meet exactly those on the land.
