Engineers must observer the speed of trains within their control. They must also make any adjustments in throttle setting necessary to maintain proper distance between the train in the block and preceding or following trains. Engineers must not stop trains in their blocks with the rear portion of the trains extending into another block, except in an emergency, in which case the engineer stopping a train must ensure that the engineer in the block affected is aware of the stopped train. Under no circumstances will a Yardmaster or Local Operator take control of a block or throw a turnout on any portion of any mainline track without the knowledge and permission of the Tower Operator in charge of that block. CVL Radio Operations Remember that the best radio is the silent, available radio.
Radios are only to be used to train operations, emergency situations, and layout security.
Only the Coordinator, Dispatcher, Tower Operators, Yardmasters, and Local Area Operators should use the radio at any organized run, except that the Coordinator may designate Monitors to use radios for security purposes. The precise problem must be conveyed to the Dispatcher, who will instruct the Tower Operators in how to respond to the situation. This will ensure smooth, controlled response, not a panicked shutdown of the complete layout. Proper format is to first state whom you are calling, then state who you are. Once you have gotten an acknowledgment that the person you are calling is ready to receive your message, state it briefly.
