Not at all boring Andy - and they will no doubt help others. Being honest I don't know that GoW bulbs are widely used any longer and you seem to have some there that require less than 12V. Let us know if we can help. R-
Not sure if I have plenty of time on my hands - or I’ve simply forgotten to do something really important.

Thanks Rogerb

These latest lamps are advertised as "10pcs OO/HO Scale Model Lamppost Street Lights 12V Railway Yard Lamps Lights" and sold from a shop in Basildon. On closer inspection though, the seller is in China :roll:

I have also bought some Expo 12v amber bulbs so I'll see how they pan out.

Might be worth getting LED lamps. They use less power and don’t get hot and last for years.

Made some more progress yesterday and built up the extension units for the fiddle yard and run-off track. Board kits supplied as usual by Model Railway Solutions.

Basically, when viewed from the front of the layout, a train will exit the left Helix onto a single track then onto one of 3 tracks provided by a 3 way point into the fiddle yard. Overall length of the fiddle yard board is 5ft but usable track probably 4ft. The 3 tracks then merge into 1 via another 3 way point, then leaves this area and runs round the back of the right hand Helix and rejoins the layout.

I will fit a point to join the fiddle yard exit track to the single line that runs through the middle of the layout Goes under a bridge and vanishes). This way, I can run a loco from the fiddle yard, round the back of the right hand Helix, then reverse down the single line into the centre section. Bit of variety and all that :roll:

https://flic.kr/p/RHdcFS You have a serious Wrong Side signalling failure there!!! Proceed aspect (green) leading onto a point set to the turnout direction. The Railway Investigation Branch will be calling later! :D

Love the size you have available. Great work Andy.

All track and points laid on the extension boards today. I have also wired in the additional 8 point motors but I have one question.

Could I operate 2 points by one switch and if so, how ?

I have a crossing on the extension and it makes more sense to operate both points with just one switch.

Depends on how you are operating the motors and how the points are wired, but yes usually you can. R-

All points are controlled via their own power source and each has it's own switch. So at the moment, each point is thrown from a control panel. I tried connecting the two points into one connector block then ran the wires off to the switch. I then set the points as if a loco would be crossing from one to the other. One point throws, then when I throw the switch again, the other one throws.

I then re-wired them back to having their own switches. So at the moment they are still acting separately.

Having wired the track and points on the new extension boards, I am very pleased (surprised) that I had very few problems with polarity etc.

See, I have learned from what people tell me :mrgreen:

I think I read earlier that you were using Seep motors?
If so all you need is to add a couple of link wires between the motors. Start by linking terminal A on one to terminal A n the other. Do the same with the B terminals. This will mean that either switch will throw both points.
If you end up with one point open and the other closed just swap the wires A to B and B to A and they should then either both be open or closed.
Deja Moo: The feeling that you've heard this bull before. ;)
