Which of the following is NOT a responsibility of an Amtrak lineman?

An Amtrak lineman is primarily responsible for tasks associated with the maintenance and repair of railway systems, which include the inspection and testing of various components relevant to safe and efficient train operations. This role involves ensuring the functionality of electrical systems, maintaining track integrity, and testing railway signals to assure safe passage for trains.

Operating the train, however, is a distinct responsibility that falls under the purview of train engineers or conductors. These positions require specialized training and certification to handle the operation of the train itself, manage train movements, and ensure adherence to operational protocols.

By identifying operating the train as not a responsibility of an Amtrak lineman, it underscores the specific focus of the lineman's role on infrastructure and support systems rather than on direct train operation.
