-The BC3 is an automatic block control system otherwise known as SuperBloc (QV). It controls the speed of a model train depending on the occupation of the block ahead. If the block ahead is occupied the train will slow to a creep speed and stop at a designated point. Otherwise the train will accelerate to a preset speed. Manual control is also allowed for. Kits for the [[:kits:38|BC3]] and literature about it is available from MERG - TBs T33/0-20.\\
