Indian Locomotive Class WAP-4
WAP-4 is one of the most important electric locomotives used in India. It is a very powerful class, capable of hauling 26 coaches at a speed of 130 km/h. It is also among the most widely used locomotives.
The locomotive was developed, after a previous class WAP-1 was found inadequate to haul the longer, heavier express trains(24-26 coaches) that were becoming the mainstay of the Indian Railways network. It was introduced in 1994, with a similar bodyshell to the WAP-1 class, but with Hitachi traction motors developing 5000 hp (5350 hp starting).
Electricals are traditional DC loco type tap changers, driving 6 traction motors arranged in Co-Co fashion. This locomotive has proved to be highly successful, with over 700 units in service and more being produced. Newer examples have been fitted with Microprocessor Controlled diagnostics, Static Converter units (instead of arnos) and roof mounted Dynamic (Rheostatic) Brakes.
The locomotive can be seen in service across the electrified network of Indian Railways and are homed at 13 sheds (depots).

Famous quotes containing the words indian, locomotive and/or class:
“The Jew is neither a newcomer nor an alien in this country or on this continent; his Americanism is as original and ancient as that of any race or people with the exception of the American Indian and other aborigines. He came in the caravels of Columbus, and he knocked at the gates of New Amsterdam only thirty-five years after the Pilgrim Fathers stepped ashore on Plymouth Rock.”
—Oscar Solomon Straus (1850–1926)
“A bill... is the most extraordinary locomotive engine that the genius of man ever produced. It would keep on running during the longest lifetime, without ever once stopping of its own accord.”
—Charles Dickens (1812–1870)
“Alas for the cripple Practice when it seeks to come up with the bird Theory, which flies before it. Try your design on the best school. The scholars are of all ages and temperaments and capacities. It is difficult to class them, some are too young, some are slow, some perverse. Each requires so much consideration, that the morning hope of the teacher, of a day of love and progress, is often closed at evening by despair.”
—Ralph Waldo Emerson (1803–1882)
