Re: Y turnout

Diagrams no use. I shall attempt a simpler explanation. Forget the Y point is inverted. It actually is so if looking at the layout, but it is immaterial. The stem of the Y is connected with normal fishplates/RJs to a very short dead end siding. One arm of the Y, fitted with 2 IRJs, connects with tra...

Re: Y turnout

Think of the Y inverted. The top is connected to the dead end siding with normal fishplates

The two lower arms are fully insulated with 4 IRJs to the two spurs leading to the main

Re: Y turnout

Flashbang Right thanks again - I think I understand, but as the Y is in situ, pinned, glued and ballasted and only insulated at the the two arms it could be tricky to effect! Plan B then At the head of the Y is a siding - just for the loco. This also joins to the Y point proper with no IRJs but with...

Re: Y turnout

Flashbang Thanks for the link - useful - and electrofrog Y. Still unsure of your solution. Surely the DCC feed has to be reversed somehow if the loco is to travel down the other arm of the Y? I have done this with a DPDT for the DCC feeds only. Also If you have the IRJs as shown on the end of the Y ...

Y turnout

Chaps DCC layout and wiring up a Y turnout to enable loco to reverse direction when running on the main - this via two normal turnouts to the main. I have a DPDT switch in place to reverse the (polarity?) of the short section of track from the head of the Y to facilitate the changeover in wiring req...

Trees,bushes scrub etc

Chaps Looking at using small springs of green heather for use as small trees and bushes - perhaps sprinkling on a little flock for a more realistic result. Any ideas as to how to preserve the dark green natural foliage of the heather - spray lacquer perhaps Additionally looking for cheap ideas for t...

Re: PM1 point motors - another questions please

It is a plug in style transformer for a laptop. Made by Hewlett Packard fitted with a standard mains plug with the inbuilt problematic 1A fuse. Wiring from this plug to transformer is pretty thick, nothing detrimental there I think. From transformer it goes to the points bus wiring. Input 100-240V A...

Re: PM1 point motors - another questions please

Yes, I appreciate it a non-standard rating. As I say, it is used as a fuse for the mains plug for a laptop power adapter/transformer. I also appreciate a need for a 3A, but the 1A is dimension-wise smaller than "standard" fuse size, so I need something rated at 3A but same size as the 1A.

Re: PM1 point motors - another questions please

Gents My thanks for this. Yes, basic electrical theory returns thanks to your prompting! Fuse is in the mains plug of the PSU power supply - the transformer plug that is. I now appreciate the need for something bigger.....but strange it did not blow before now... Ordered a CDU anyways from micro-mod...

PM1 point motors - another questions please

Chaps Pursuant to a previous post - and my thanks for all replies - to power the PM1s dotted about the layout - 7 so far, I have used a laptop transformer/adapter as the DC power source. So far, it has worked well, but lately has been blowing the fuse, which is a small 1A in the mains plug of the tr...

Re: PM1 point motors

Splendid idea re the peg - I like it. However, further investigation revealed the microswitch not being conductive at all. Continuity test using the meter showed nothing at all between the common - the frog - and both of the inputs - in my case the DCC. Quick spray with acetone on the motor - used f...

PM1 point motors

Chaps I have a number of PM1 motors dotted around the layout which work pretty well at switching point direction - Peco 75 track, DCC, OO. They were purchased with the added benefit of wiring in the frog to the inbuilt microswitch, which until today, I had not tried out. However, as locos tended to ...
