The chassis is separate from the superstructure, being held in place by a bolt, which engages with a nut hidden in the smokebox, a tongue and groove arrangement secures the rear. An ABC Gears Mini 7E with an M1824 motor and flywheel fits comfortably into the boiler which is cut away to accommodate the mechanism. Pick-ups are 0.5mm phosphor-bronze wires bearing on the back of the left-hand driving wheels, while those on the right are uninsulated. I'm working on a pick-up from the front carrying wheel too, which should further improve performance. There's a surprising amount of detail on this little engine and it won't be complete before its first trial outing on the the club layout in Carlisle early next month.

| The motor is supported on a cross bearing just behind the flywheel to keep it from resting on the axle. |
 |
| Using an M1824 motor allows just enough clearance inside the cut-away boiler. A sand box will be mounted behind the motion plate. |

| Buffers are from Roxy Mouldings and are mounted high on the buffer beam, so the retaining nuts are too big to fit under the footplate and an alternative needs to be designed. |
