Re: The Burford Branch

Thanks, Tony, and also Keith. The original switches for the electro-magnets couldn't handle the 3-amp demand placed on the circuit by these particular electro-magnets, so they were replaced with higher-rated switches, which I largely avoided using other than for testing , before the diodes were inst...

Re: The Burford Branch

I have had very little time for any hobby activities in the past few weeks, due to having to spend all my time completing a professional writing project to meet a tight deadline. I did, however, find the time to do the battery test on the layout suggested by Keith Norgrove. With no electrical equipm...

Re: The Burford Branch

Thanks, Tony.

I was thinking of looking at it with my multi-meter, and this is something I'll do next week, in addition to the battery test mentioned above.

Re: 17/18 October - Missenden Virtual Autumn Weekend

I would have been interested in this virtual event, but simply didn't have time last weekend to go online.

Is the recorded material by any chance still available, and if so can a link be provided to it?

Re: The Burford Branch

As I mentioned yesterday, I won't be able to try the battery test suggested by Keith until next week, but I should perhaps make it clear that the dull glow from the LED when it is switched 'off' doesn't greatly bother me in itself. My real concern is whether the 'stray' current that makes the LED gl...

Thanks, Keith. I'll try that. I'm currently 90 miles away from the layout, so it will have to wait until next week.

Re: The Burford Branch

I don’t understand electrical and electronic symbols, so please excuse the crude form in which this diagram is presented. LE...

Re: The Burford Branch

An LED conundrum Some time ago, I decided to add a panel indicator to the switch panel that controls the electro-magnets for uncoupling the magnetic couplings on the layout. At the time, there was a risk that a switch might inadvertently be left on (as I was not using push-buttons for this purpose ...

I showed a photo a few weeks ago of the new choc-block under the baseboard after it was wired up. The final job w...

Re: Scale Clocks

You could, of course, dispense with the clock altogether, and just run through the sequence (the times shown in the WTT being purely nominal).

I wrote a letter in the Railway Modeller making this suggestion as long ago as 1966 (!)

Re: Caution: Testors vs POWsides

I applied POWsides rub-down transfers to a PO wagon, and then sprayed it with Testor's Dulcote direct from the can.

I had absolutely no problem after spraying Dulcote on the wagon sides. In fact, I was very pleased with the result.

My understanding is that the question posed related to the working of the local pick-up goods train, calling at all stations to drop and collect wagons.
