Fitted the gantry at the LM Jc today, with it's associated servo gubbins.
Wired up to 12vdc, lit up and operative via on/off switches it twitched and grumbled into life, settling down to relative silence about 15 seconds after each activation.
As you can see there is still a little bit of "stand off" on the 2 miniature arms but this is mechanical rather than anything to do with the servo action. A little adjustment will be required.
Still a bit buzzy sometimes but nothing serious.
Steves County class 4-6-0 does the honours as the first train past it with the route set towards the fierce incline up to the GW station.
