Re: Seep PM-1 on DC Layout

A and B are the two coils C is their common return, D and E are the two contacts of a change over switch , F is the common. You can use the switch for frog polarity switching, or to operate panel indicator lights or signals.

Re: A cure for insulfrog points?

I was just looking at my already laid track and is seems not all frogs are the same. Some have a longer plastic frog yet all are peco track. :? Has anyone else noticed this? End2end It all depends on the Age of your Peco point and whether or not they are Streamline or Setrack. They seem to have cha...

Re: Points \ turnouts \ switches and polarity on DCC

Lets go through them point by point (was that a pun) Insulfrog points have a dead section at the tip of the frog, there are some things that people have done to overcome it, they all come fairly close to a bodge. The clips that Hornby sell are for an entirely different problem. An insulfrog point ca...

Re: A cure for insulfrog points?

These mods are all more or less emulating what Peco have now done with their universal frog. One of those ideas which cause you to think "why the hell didn't we do this to start with?"

Re: Shunting Puzzles Solution Formula’s

First step is to define a way to express the problem. Then take a look at the Algorithms of the various computer list or stack sorting routines, I'd think one of them would be a pretty close fit. You actually have an advantage over most computing routines in that you have more than one place to use ...

Re: Shunting Puzzles Solution Formula’s

Don't know if there's a general solution, but for a specified problem it should be possible too write an algorithm that will predict the minimum number of moves required, but I'm not volunteering to do it.

Re: Drawing Software for Mimic Diagram?

If you want something that gets printing sizes right without fiddling around, lets you draw lines and shapes in different weights and colours, and even lets you integrate bits of bitmap pictures, take a look at the drawing app in the free "Libre Office" suite. It does a pretty good job on ...

Re: Daisy Wanted.

Now might be a good time to buy your donor models. Plenty of relatively cheap ones and some ridiculously expensive ones. Bear in mind that if you want it to run on modern track the original Triang motor bogie will come with fat wheels which will need replacing or modifying, so a couple of dummy trai...

Re: Pins or glue

If your baseboard is ply the long Peco pins will bend if you try to tap them in. Use a pin driver, pre drill with a headless one gripped in the chuck of a small Archemedian drill, or off you are desperate, grip them low down with fine pliers, push them in as far as the will go, bend them over and sn...

Re: Dead on shelf.

If the decoder is in a socket, take it out and refit it, wouldn't hurt to do it two or three times then try again. A non conductive film can develop between the contacts of the decoder and socket, the friction of taking it out and replacing it can break down the film and restore contact. I think thi...

Re: A new start in Finescale OO: NSR Stone junction station

I have a few spare pinpoint axles from using their wheels to rewheel Ringfield motor bogies. I've made brass pinpoint axles in the past, but doing it in the three jaw chuck of a hammer drill isn't very reliable. Wound up with too many short ones with blunt ends.

Re: reversing loop on a single track?

In DCC you'll need a reverse loop module and all four rails insulating at the ends of the loop. In DC either wire it through a DPDT (Reversing) switch or if you are happy for trains to always run in one direction use a bridge rectifier, either way the DC controller will need to be reversed when the ...
