What is diesel engine electric traction?
Diesel-electric traction represents the use of the diesel engine with the petrolelectric system of traction, both of which were invented in the 1890’s.
What are the advantages of diesel-electric traction?
Compared with steam, the diesel traction unit had a number of major advantages: 1. It could operate for long periods with no lost time for maintenance; thus, in North America the diesel could operate through on a run of 3,200 km (2,000 miles) or more and then, after servicing, start the return trip.
What are the disadvantages of electric traction?
Disadvantages of Electric Traction Drives
- Requires high capital cost.
- Less flexibility of the routes.
- Can cause interference with nearby communication lines.
Do diesel trains have gears?
Its idle speed is around 269 rpm, and its maximum speed is only 904 rpm. With a speed range like this, a locomotive would need 20 or 30 gears to make it up to 110 mph (177 kph). … By going with a hybrid setup, the main diesel engine can run at a constant speed, turning an electrical generator.
Are steam locomotives more powerful than diesel?
