The layout was constructed to make transport easier and safer than a previous, similar, layout. The length was extended to five feet, the width was extended to eleven inches. The size increase allows no increase in complexity, the operation of the earlier model was successful and proven. It did allow SMP Finescale track to be used rather than the earlier's universal track system.
The operation still revolves around swapping locomotives around in a set of sidings theoretically adjacent to King's Cross Station London. A card system is employed to allocate locomotives to a "spot". The model was inspired by the old King's Cross stabling point. Public operation is encouraged. This model is used as part of a stand based around the theme of "No Room/Time For A Model Railway?" A table top display of between 1-4 small layouts, for discussion AND operation.
