Mainline crews communicate with tower operators, when needed, via train phone. Train phone is simulated via lineside telephone.
Secondary crews communicate with tower operators via lineside phones. Locations of lineside phones are indicated on fascia control panels and represented trackside; locomotives/cabins should be stopped close to lineside phones for the convenience of the crews.
Until such time that lineside phones are implemented, crews shall walk to the tower operator to communicate. The act of walking to the tower operator shall simulate the act of walking to the lineside telephone. FRS radio shall be used temporarily between the yardmaster and the tower operator.
