    Eric's M-track replacements

    Eric it was mentioned sometime ago that there was an error in the #20 turnout pieces and I found that you could not get a complete route through them (gap in yellow line) and so for that reason, all power turnouts on the CNO&TP 2nd district are #15. I know, since I had to repair a lot of measureing devices that didn't like #20s that those #$%^&*() turnouts on the CN&TP 2nd district were #20s. Another turnout you might think about adding to the set would be a #20 equilateral turnout. Looks like a "Y" turnout. These are used on nearly all ends of double track on the CNO&TP and Southern Rwy. Eastern lines, i.e. Washington to Atlanta. So, were you able to fix that error? Under SR rules, the #20 was good for 35mph and the equilateral being the equivalent of a #40 in diverging was allowed up to 60mph for passenger, 50 for freight and they may have loosened those by now, some more.

    The stretch between Tateville & Greenwood, KY was single track on the new line when I worked there, now it is double. Back then, there was a spur just before the end of double track going north near KD tower and since we were always held up a few hours there to let Per Diem trains go by, we used that opportunity to make more serious repairs. I can remember in the minds eye, those NB big trains, usually 2-SDs on the head and 2 more at the RMU set settiing up a very loud dynamic brake howl going past.

    I think it's a documentation problem on the No24 and No20, Jerry.

    If you see the purple boxes below, a 9.6m straight between the turnout and the frog/end on the No20's allows it to line up.

    For the No24's, you need an 8.5m straight between the frog/end and the turnout.

    TSRE also doesn't seem to do well with note ends being too close together, so I had to work towards the turnout to get everything to line up.

    Left to right: No15, No20, No24

      Number 24 turnouts are pretty rare. There are probably some in use on the so-called 110mph Amtrak between Chicago & St. Louis, and probably on the NEC.
      I'll keep the #15 turnouts on the CNO&TP segments as the track is already laid, but I'll try this on any future routes.
