Hi Would like to know if the code 70 assembly jigs can be used with ME code 55 rail. All my jigs are for code 70 and I wouls like to do some code 55 turnouts and track for use on industrial sidings. Thanking you in advance Ian Holmes |

Ian, Yes - but, you'll have to include use of track gauges while constructing. The bases of the c55 rails will be sliding back and forth in the rail groves, so you'll have to have track gauges keep them aligned. The real cautions are the frog flangeways and the guard rail placement. Understand and set the track check gauge correctly. -ed- |

Hi Ed, Would the Micro Engineering tri-point gauges work in this instance? Donnell |

Donnell, Yes, good choice - at least for gauging all the running rails. I would also give consideration to using some of Stephen Hatch's (Railway Engineering) "Rollee" two point gauges. Use the NMRA gauge for the flangeways and the guard rails. The c70 fixture will give a lot of 'slop' to the wing rails positioning and the guard rails placement when fitting with code 55 rails. Read RP-2 (or the instructions that come with the NMRA gauge), and be certain that you understand flangeway is NOT the larger nub and exactly how the track check gauge is set for the guard rails. Flangeways at the frog (wing rails) should be as wide as possible and yet NOT exceed the maximum. P.S. I highly recommend using the NMRA gauge checking of the flangeways and the check gauge when using even the rails specified for the fixture. These areas are critical, and the fixture does have just enough grove leeway to allow ever so slightly non-conformance construction when just blindly laying in the rails. One gets accustomed to knowing which way to press the wing and guard rails for a correct fitting after a few trials checking with the NMRA gauge. -ed- |

Thanks Ed for all the information. I will take some time to mull it all over. i was considering getting C55 fixtures but I dont know if I can justify the costs at this point Cheers Ian |
