Stop & Proceed	Stop, then proceed at Restricted Speed until the entire train has cleared all interlocking and spring switches (if signal is an interlocking or CP signal) and the leading wheels have: 1.

In CSS territory, trains with operative cab signals must not increase their speed until they have run one train length or 500 feet (whichever distance is greater) past a location where a more favorable cab signal was received. Where identified by special instruction, or where a letter G (grade marker) or a letter R (restricting marker) is displayed in addition to number plate as part of these aspects, freight trains may observe the signal as though Restricting, Rule 290, were displayed.
