Exercise 2
Listen to and translate the following sentences in which the new words and word combinations are used.
1 Locomotives designed to haul freight or passenger trains are called road locomotives.
2 A yard switcher locomotive moves cars from track to track in railroad yards.
3 A general purpose locomotive can be used to haul trains or for yard switching
4 Most diesel-electrics have generators that produce direct current (DC), a kind of current that flows in only one direction. Generators on some newer, large diesels produce alternating current (AC), which reverses direction many times every second.
5 The action causes the turbine to rotate and to drive a system of gears and shafts that move the wheels.
6 Most electric locomotives in Ukraine use alternating current. They obtain the power from an overhead wire called a catenary.
7 A hinged steel framework called a pantograph, which conducts electricity, connects the wire with the locomotive.
8 Steam locomotives produce heat by burning coal or fuel oil in a firebox.
9 The contact shoe slides along the rail and picks up electricity from it.
10 Diesel locomotives can make long runs without refueling, or servicing. They can be quickly stopped or started.
