A viaduct on stone piers for linking my high level stations, bridges, etc. all of which have names beginning 'DDD HL ...'. 10 metre segments, end stone pillar which should be placed away from the scenic object to which the viaduct is attached. Use 'grey conc std clean ...' track (TS2010 built-in) to attach the viaduct to any 'DDD HL ...' scenery object.
