A mechanical shunting disc signal as produced by the LMS and later by BR with white track circuiting diamond. These signals are often placed on main running lines to control reversing movements accross the lines or into sidings. Mesh and textures by francelinetony, using bloodnok's signalling script and thanks to him for agreeing to the release of this model. Thanks also to Chrisaw for his help in creating this model. This is a version that sits closer to the track, for those tight yards or other situations, modified by Davie_UCF with permission.
