I would suggest that the lack of rail
would have done the job most effectively.

No, that would have prevented broad gauge trains from *succeeding* in going
the wrong way. It wouldn't have stopped them from attempting and derailing,
if the points on the shared rail were wrongly set.

No broad gauge rail. The track would be something like this:

Wow, thanks, that was service beyond the call of duty. All is now clear.

I've always wondered if you type these ASCII diagrams by hand or if you have
some program for doing them.

By hand. Though I've now done enough that I have a good feel for how to
put them together. And vi is a very sharp tool.

A

Irrespective of the setting of the points, the check rail C would
pull a broad-gauge axle around the curve.

Well, it would try to, but wouldn't the point at A try equally hard
to put the wheel on the wrong side of the rail? Or is there something
special about the bit of track on that side too?

Argh, you're right. Fixed points, with a gap where the blade is, works
to split the two gauges, but it doesn't work in conjunction with a
turnout. Back to the drawing board.
