Locomotive FAQs:

Q: Were locomotives built by Cornish inventor Richard Trevithick?

A: Yes.

Q: Are locomotives often subdivided in their usage in rail transport operations?

A: Yes.

Q: Was a locomotive some two and a half times that of diesel power?

A: Yes, and the daily mileage achievable was far lower.

Q: Is a locomotive loaded or unloaded in about a third of the time?

A: Yes.

Q: Was a locomotive first experimented with in 1920?

A: Yes, and reaching its peak in the 1950s to 1960s.

Q: Are locomotives normally designed to deliver high starting tractive effort—needed to start trains that may weigh as much as 15,000 long tons —and deliver sustained high power?

A: Yes, and at the sacrifice of maximum speed.

Q: Was a locomotive Salamanca on the narrow gauge Middleton Railway in Leeds in 1812?

A: Yes.

Q: Was a locomotive demonstrated in Val-d'Or?

A: Yes, and Quebec.

Q: Is a locomotive a non-powered unit attached to a diesel-electric locomotive to provide additional traction and braking capability?

A: Yes.

Q: Are locomotives capable of higher performance and lower operational costs than steam or diesel power?

A: Yes.

Q: Are locomotives diesel-electric?

A: Yes.

Q: Were locomotives produced before then?

A: Yes.

Q: Was a locomotive Matthew Murray's rack locomotive?

A: Yes, and Salamanca, built for the narrow gauge Middleton Railway in 1812.

Q: Is a locomotive supplied externally with electric power?

A: Yes, and either through an overhead pickup or through a third rail.

Q: Were locomotives not built until after Dr?

A: Yes.

Q: Are locomotives very powerful?

A: Yes, and very loud.

Q: Were locomotives first built just after World War I?

A: Yes, In the 1940s, they began to displace steam power on American railroads.

Q: Were locomotives a series of narrow gauge locomotives built by Richard Hornsby & Sons Ltd?

A: Yes.

Q: Are locomotives designed specifically to work steep grade railways?

A: Yes, and feature extensive additional braking mechanisms and sometimes rack and pinion.

Q: Was a locomotive built using a 12 hp double-acting marine type engine?

A: Yes, and running at 300 rpm, mounted on a 4-wheel wagon chassis.

Q: Are locomotives used in mines and other underground locations where diesel fumes or smoke would endanger crews?

A: Yes, and where external electricity supplies cannot be used due to the danger of sparks igniting flammable gas.

Q: Is a locomotive less likely to deviate from its normal course?

A: Yes.

Q: Are locomotives still used on shunting duties around Bulawayo and on some regular freight services?

A: Yes.

Q: Are locomotives often fitted with "dynamic brakes" that use the traction motors as electrical generators during braking to assist in controlling the speed of a train on a descending grade?

A: Yes.

Q: Were locomotives in regular use until 2004 in the People's Republic of China?

A: Yes, where coal is a much more abundant resource than petroleum for diesel fuel.

Q: Are locomotives less efficient than their more modern diesel and electric counterparts and require much greater manpower to operate and service?

A: Yes.

Q: Were locomotives powered by steam?

A: Yes, and usually generated by burning wood, coal, or oil.

Q: Are locomotives also used on many underground railways for maintenance operations?

A: Yes, as they are required when operating in areas where the electricity supply has been temporarily disconnected.

Q: Are locomotives reciprocating units?

A: Yes, and in which the pistons are coupled to the drivers by means of connecting rods, with no intervening gearbox.

Q: Was a locomotive built by Richard Trevithick?

A: Yes, it first ran on 21 February 1804, although it was some years before steam locomotive design became economically practical.
