Re: Your first train ride you can remeber

I've got two sort of snatches of memory of train rides from when I could have been no more than three. One is of sitting at a table in an open saloon carriage, with Mom and Gran looking out over a busy junction station. It was on a journey from the midlands to Yarmouth, I guess the loco was being ch...

Re: One way travel

This is definitely a situation made more complex by DCC. It has already been said that in DC all you need is an isolated rail and a diode. Not quite! the problem is a little more complex. As Brianetta suggests a physical end stop (bufferstop) is almost essential. I had a similar setup on my last lay...

Re: point motors 16v or 24v AC ?

I Use 16V AC and a CDU and still a peco double-slip is reluctant to throw both ways on each side. I can't see a way of adjusting the spring tensions like the turnouts (by moving the plastic square back) As suggested check out the wiring size. Also you don't say how the point motors are attached. If...

Re: Bachmann E-Z controller

Care to guess which way the real railway works? Are you referring to the outfit who, for no apparent good reason, relaid a curve so that it was tight enough to make the flanges squeal! Then got complaints from the neighbours. So what did they do? Installed a row of industrial sized lawn sprinklers ...

Re: Prototype research

Old large scale maps as suggested plus the books and going to look for yourself. The layout of Bescot Junction has changed over the years, but I can still see what was the foundations of my uncles signal box.

Re: Stay-alive capacitor hacking

Well if you want electrofrogs in this geometry, just modify the frogs with conductive paint :D (you can get it) Andrew Yep - I've got a (very)little tube of it. Great for mending PCB tracks, replacing with Peco points may actually be cheaper! it's actually colloidal silver. It can work but it's not...

Re: Newby Questions

Hi PC_GEEK Welcome to the forum. Sounds as though you have something most of us would die for, space. You need to ask yourself these questions. 1 - will the board ever have to be moved once constructed? 2 - In-situ will I be able to reach every part of the board? 1200mm by 600mm is probably the larg...

Re: Stay-alive capacitor hacking

At a guess somewhere beyond the rectifier there's already a capacitor across the supply. If there is spiking as seen by martin71, a capacitor is going to convert it into a higher steady voltage. It'll be Interesting to see what happens to that voltage when you put on the bigger caps. I think a small...

Re: Stay-alive capacitor hacking

Now i've seen your video (had to wait for the old broadband to climb back to a decent speed) I think I know where the 27v comes from. The track voltage is 15v AC with a control signal superimposed on top. Your meter expects a constant voltage on DC not what's present at the points you are measuring....

With the answers you got it would be fair to say that you found yourself in exactly the same position as EWS after they bought the 67s and lost the mail contract.

Re: Foam Baseboard and Point Motors

Bufferstop - not sure that I'm too keen to cut my points... :) You only need to do anything to the points if your using Setrack or Hornby, where there are rail joiners spot welded to the rail. Streamline points come with no joiners and you cut the sleeper fixings on the adjoining track. As I said h...

Re: Stay-alive capacitor hacking

OK! seems you have a value to work with now and if you want to do it for it's own sake I'll not argue agin it. I'd definitely try to introduce some vertical movement into that locos axles though. Just enough for the non driven ones to drop a little. Just enough that if you hold it in the air and put...

Re: Stay-alive capacitor hacking

I have one set of two points facing away from each other which is a particular problem; the track top height on one of the rails seems to be a few microns lower than the one it's fishplated to, and the length of the loco so unfortunate, that the loco ends up with two diagonally opposite wheels sat ...

Re: railway crossing sounds project DIY

Had the grandkids round last weekend. They have a big box of "Megablox" (like giant Lego) and amongst it are a couple of units which have 2 buttons and a trumpet like horn. Pressing the right sequence on the buttons allows you to record a few seconds of sound, which then plays back when a ...

Re: Chiltern Line A4

It's amazing how far a loco's whistle carries. About a mile from our house, across open fields and behind a small hill there's an accommodation crossing with whistle boards. We rarely here the horns of the Sprinters which are up and down every hour, but in the Summer when the Shakespeare Express is ...
