According to Wikipedia it's 18. So for TT something like 0.15 to 0.175 inches should look about right. But I suppose you have to take into account the tie thickness too, a thicker tie would presumably look better with a bigger gap.


The tie spacing depends on the type of the track, railroad, and era.
Here is Pennsy's track spacing as an example:

Maybe not worth getting too fussy about then. The Pennsy's spacing for yards and commercial sidings was near on 2 ft 6in, and I daresay other railroads had similar. So for my purposes the spacing of the ties as supplied should do fine.

A couple of months on and I've managed to get the track laid, wired and sprayed.

You can see the wooden pushrods I use to change the points. They also operate microswitches which change the polarity of the frogs.

And...I added a run-round after all. Given that it also serves as storage while switching, I haven't really lost anything by ditching a siding.

Here are a couple of photos showing the fiddle yard. It's 20in. long, or half as much as the layout itself. I've designed it as a sector plate, so the length of wood the track is resting on swivels at the back end to swap between two tracks if need be. (The track in the photo isn't fixed down yet.)

The gap at bottom left is to accommodate the post for a lighting gantry, as yet to be built.

Also on view are the legs for the fiddle yard and layout, they are simply in the form of an upside down table and the baseboards just rest on them. This way I can easily get underneath the layout if I need to.
