Question: 1 / 400

Which track is used to spin a single car?

Turntable

The correct choice is a turntable because it is specifically designed to rotate a single rail car 180 degrees. This mechanism is particularly useful in facilities where space is limited or where cars need to be repositioned without requiring a full track layout. Turntables enable efficient movement and storage of rail cars by allowing them to be turned to face the direction needed for their next journey.

In contrast, a transfer track is primarily used for moving cars between different tracks rather than for rotating them. A double-ended track, while allowing for trains to exit from both ends, does not provide the rotation function. A service track is mainly utilized for maintenance and servicing of rail cars, not for repositioning them through rotation. Thus, the turntable is the optimal choice for the purpose of spinning a single rail car.
