CTM Forge 1.3

The lead car of each train now has a triangular tip, and is now colored differently to visually distinguish it from the train's other cars. The map_style.colors.lead_car config option can be used to change the color.
Chain signals are now triangular, pointing towards the next signal. The colors still reflect the state of the signal.
Signals can now be configured to display on either side of the track with the map_view.signals_on option.
(Forge) Move config file from defaultconfigs to config where it should be.
