Simple DC Controller

I only have two standard gauge locos at the moment - a GWR 55xx prairie which is so far just a rolling chassis and also a Heljan Class 42 Warship. Both of these are still DC but will be converted to DCC in due course. The Warship takes quite a lot of power - and the little old Gauge Master DC controller borrowed from my son's trainset would frequently cut out. 

I didn't want to splash out on a high-power DC controller, so though I'd try one of the cheap PWM motor controllers that are now readily available - I think driven by the rise in e-bikes etc. I bought this one which was a 20A 25KHZ PWM DC Motor Controller which cost a mere £17.99 from eBay:

I hooked it up to a 16v DC old laptop power supply that I also use for my NCE ProCab and tried it out. It works a treat. There doesn't seem to be any noticeable buzz etc from the locos and I think it will certainly serve well while I'm completing the SG.

Traverser installation

 The traverser has returned from its travels. I built it for O14 at ExPong 2014 and then gave it to David J as I had no use for it. He's had two house moves and now didn't need it, and as I could use it in the new config it has come to Devon.

It will be adapted to have two mixed gauge tracks. I've nearly finished the two curved spline roadbeds for SG and NG which connect to the traverser. The NG has a tight curve and ducks under the SG.
