A detailed working model of a SR ladder style post distant or caution signal.
This detailed operating signal features LED lighting, shining through the red or green lens of the signal arm depending on position and a fine etched steel ladder. The signal fits through a 13mm diameter in the baseboard, allowing the motor and electronics to be fitted out of sight below the baseboard. Supplied ready for DC operation, conversion to DCC is possible using a static accessory decoder (not supplied).
