A detailed working model of a LMS upper quadrant junction signal with the short post to the right.
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).
