    Steve,

    My story sounds identical to yours! The problem area is on a curve that leads to a very short straight section prior to the bridge. I am assuming that by "pinching" you mean the rails in the problematic area are out of gauge. If that is the case then I am in DEEP POO POO!

    One thing I neglected to mention was this damn 2" section of track starts about an 1" inside the right end of a fairly short tunnel. Short of removing the top of the tunnel (cutting it off) and replacing the track it looks as though the easier option, and less frustrating one, maybe to start yet ANOTHER layout for the wife

    Tony, I too ran into the same problem a while back with my tight radius loops. I had the same issue as aflica and was effecting the rail spacing. Have you run a gauge around that section?

    Olie,

    It is sounding more and more likely that it is a gauging issue but no, believe it or not I don't own a track gauge. Seems as though I should get my hands on one. The "only thing" I don't understand, and I am not questioning the probable cause for the problem, is why it becomes progressively worse the more laps the train does. If the track was/is out of gauge, wouldn't the issue be constant? As said, I'm not questioning the validity of the probable issue, just trying to understand it.
    Cheers Tony

    Any conductor will have some resistance, even if small. Resistance in a conductor equals heat. Ideally the heat generated is small (unless you want heat, like in a soldering iron, hair dryer, space heater, etc.) but even a little bit of heat over a length of nickel silver track will cause expansion of those rails, that expansion over some 10 feet or so of track could be enough to change the gauge at the point you've indicated your problem. A change of just 2 or 3 hundredths of an inch could be the difference between in gauge track and wheelsets binding through a curve. That's not a lot.

    The solution may be to reduce resistance (adding feeders, especially close to your pinch point) or cutting expansion gaps in your rails elsewhere. Or both. Otherwise you'll probably have to relay your track.

    Yes that is exactly what im saying . My little problem spot was less than a locomotive long . They wouldnt derail and even finicky rolling stock wouldn't , just slow down a wee bit and you could hear that in the motor noise changing when it was in that very short section . And it was on the full curve part of the radius . It was so slighlty out of gauge , that i could not see it , only running the NMRA gauge along the section showed it was indeed tight . I mean i just couldn't see it , only felt it with the gauge . Changed it out after i messed up the Peco C80 trying to gently spread it apart (it really doesn't like to be bent outwards) and popped the rail out of the ties .

    This may not be your problem , but a gauge will definitely tell you if it is or not . I suggest you add one to your tool kit , i never thought i would use mine much , but it is one of the most used tools i have . I check everything now with it , especially soldered sections of flex on a curve where the ties were removed for the joiner and soldering . I always pre solder 2 or more lengths of track together for curves that require that kind of lenght . I dont like un soldered joints in a curve , they never line up right and look natural to me if a joiner by its self is just used . And i belive its a weak spot . That is just my opinion tho .

    Get a gauge , you wont regret that purchase , and make sure it a NMRA one , it also helps support them . And it has many other uses besides track gauge

    Plus one on what Steve said. The NMRA gauge is indispensable.

    Thanks guys and I do believe it is a gauge issue. I will be getting a track gauge just to have on hand AND looks as though I am going to be rebuilding the layout - from scratch as trying to fix the issue seems like a lot of work with no guarantee of a positive result.

    The "new layout" will be slightly larger in area being (I think ) 34" X 25". These dimensions will permit 11.5" radius curves and a couple of longer straight sections front and back and therefore, will reduce the tension/pressure on the rails around the curves.
    Cheers Tony

    Okay ... this quick enough for you guys?



    Nothing fancy this time. Going back to the good old (pain in the butt) tabletop covered in layers of foam, a single main bus that will follow beneath the track work and probably be 18 gauge stranded wire. There yu have it - one layout

    Nothing done on this today as I have been putting in new kitchen cabinets, plumbing and making the counter top for them. Might get something done this evening if I can my finger out of the hot water inlet

    Quick update on this ... at the moment I am unable to do anything more as I am awaiting the arrival of Rail Joiners for the track work. Unbelievably, they arrived in East Rochester on the 27th. Evidently, it took USPS 3 days to get them from East Rochester to Rochester as it (the package) didn't get there until the 30th.

    Don't know how far that is but if it took 3 days for them (USPS) to move the package that far, it'll probably take them till the end of the year to get it a further 54 miles

    Good news - I think - my order arrived this morning so now I have all I need to make some progress with this layout, in between my real life obligations. I think tomorrow (today) I'll have the time to get a couple of layers of foam down so I can sort out the track - a simple single track oval.

    Oh yeah, logistics companies... I had two DHL shipments come here on Saturday. DHL for some reason came by twice, first package at 11:54am, second at 12:13pm. I wasn't home, first package is waiting at the post office, second one was dropped at a neighbor's...
