Exercise 1. Some words are often used together. Fill the gaps in sentences 1-8 with a word from the list that goes with the word in bold.

Unit 7. Motive Power

Start up

Exercise 1. Match these motive power units (A - F) with their names (1 - 6) and say which of them are self-sufficient (i.e. they can generate their own power).

A. B. C.
D. E. F.

1) electric locomotive, 2) electric train, 3) diesel locomotive, 4) diesel train, 5) gas turbine train, 6) locotractor.

 

Exercise 2. When you describe a chart, you shouldn’t just list the data from the chart. You should look for the more important or interesting data.

Answer the questions to describe the motive power in Russia. Use the information from the table.

1) What does this table show?

2) How many locomotives do Russian railways employ?

3) What is the principal type of motive power in Russia?

4) What traffic do Russian railways mostly carry?

 

Locomotives in Russia (2009)

Freight electric locomotives 7,417
Freight diesel locomotives 3,750
Shunters 5,989
Passenger electric locomotives 2,409
Passenger diesel locomotives
Total 20,101

 

Did you know? A shunter (or a shunting locomotive) is called a switcher in the USA. A marshalling yard in the UK is called a classification yard in the USA. A bogie in the UK is always referred to as a truck in the USA. A driver in the UK is known as an engineer in the USA. Diesel locomotives with electrical transmission are known as diesel-electric locomotives. In the USA the term ‘railcar’ has a much broader meaning, and the term is used to refer to any kind of railroad car, including unpowered freight cars.
