Today (with a little assistance) I installed the Traintronic DCC points motors that were acquired for me by Gizzy

This motor drives from beneath the point, so have to disassemble the layout. You can see the drive pin in the picture.
I then had to drill a hole through the cross bar of the point, and then through the base board. The hole through the base board acts as a pilot hole. I then had to remove the point and cut the back out of the point to allow the drive pin to move.
Once the point was removed, I then enlarged the pilot hole, this is where the motor drive pin will come through.
I then turned the board and had to cut out a recess in the board to install the motor.
I have wired up the points and clipped the wires in place. These wires are twisted as it says in the instructions to cut out interference. I will have to access these wires next week once my Massoth comes back, to set the point addresses. The thick black wire is the track power pickup, the loose wire laying across the board is the lead that will lead to the point on the next board. It has a plug connected in line to allow the wire to be disconnected when separating the boards.
Ballast all put back, just have to do something with the grass, I'll have a look at the later.
