Re: Laying track in warm weather

Leave a gap in cold weather to allow room for the rails to expand when it gets hot.
So, in hot weather, the gaps should be closed up. Perhaps leave a gap the thickness of a piece of printer paper when laying track in warm weather.

Re: DCC Conversion

How many locos are you expecting to be running at the same time? (Not just standing on the track) Are your locos modern or older models? Will you be operating your points via DCC or with separate switches? Have your existing electrofrog points been modified and fitted with frog switching? What is yo...

Re: Getting started

You can run virtually any amount of track, up to about a double garage size - and maybe more, from a starter set controller as the track consumes no power. The limiting factors are the number of locos and accessories drawing power from the controller and the way you feed the power to the rails. For ...

Re: dcc Run aways

You could try turning off dc running in CV29 and make sure the track, wheels and pickups are spotlessly clean. You could also consider fitting filters (sometimes called terminators) to the track to eliminate voltage spikes.

Just about everything electrical is covered on Brian Lambert's site, https://www.brian-lambert.co.uk/Electrical_Page_2.html Though it might not be quite as simple as you would like.

Re: Need help interrogating some decoders

The decoder tester is misnamed in my opinion. It doesn't actually do any testing. It's more like a substitute loco with various decoder sockets on board, a motor and indicator lights to allow almost any decoder to be fitted temporarily so that a DCC controller can be connected to it to test the deco...

Re: Fun with Arduino - a Series of Introductory Videos

That table of variables may not make sense to a lot of people in the UK as it is using full stops, aka periods (.) where we would use commas (,) so -32.768 for instance, would be written as -32,768 or -32768 with no comma or full stop.

Re: Need help interrogating some decoders

The only difference between the 8 pin an 4 pin decoders is the number of wires that it has. So X9659 is the same decoder as the R8215/R8249 just with a different plug and wires.

These old decoders are only fit for the bin imho although the blue dot ones may be usable.

Re: Need help interrogating some decoders

The 4 pin ones are Hornby decoders and quite old by the look of it.
I can't identify the 8 pin one with the covering on but would guess Hornby by the style of plug.

Re: Need help interrogating some decoders

If you could post pictures, I'm sure we'd be able to identify them at least.

The four pin decoders will almost certainly be Hornby. They are the only 4 pin ones that I have ever seen or heard of.
