    NSWGR Eureka HUB car modification for better tracking and stop them falling off the track at the slightest irregularity.

    With Veers getting a set and my set arriving yesterday here's a Mod I have been doing to stop the falling off the track

    Probably the most imperfect out of the box set I have ever encountered. Took me ages to identify the problem. Tried weights, etc until I stumbled on a version of your solution by just plain trial and error. Once completed then they run OK and it does not seem to affect the electrical pick up for the carraige lighting.

    Cheers

    I forgot to say that since the HUB set experience, one of my now standard tests for poor running. particularly with passenger coaches, is to cheek the freedom of bogie movement so they can cope with our ever present track movements.

    Regardless of that Murphy's law still prevails.

    Recently purchased a new set of 12 SDS NGCX wheat wagons and they all were a problem going around a particular curve. These are a particularly fine set of wagons and the detail is quite superb so very disappointed at the problem.

    Checked free running of bogies, clearance with couplers, wheel gauge.....nothing.

    Finally put a gauge over the track and guess what...for some three inches, the track had popped out of its plates and was well under clearance. So just why had the track decided to do this at the precise time I was introducing a new set? ....Murphy's law.....Installation of my 1/2 inch brads soon fixed the problem and I guess it is something I (and us all) need to watch as our layouts age and things dry out and expand or contract.

    Cheers and (now again) happy modelling

    plus something to add to the dark art?

    Hi Richard
    I have found a lot of the RTR Ozzy stuff has the Bogie screws so tight that Bogie movement is often minimal and results in derailing at the slightest ripple.

    First thing I do now with a new model is to sit down with a screw driver and check each Bogie, some even need the Bogie mounting hole cleaning up a little to stop binding.

    The Auscision, Southern Arora cars also had an issue with the one of the Bogie types “Comeng” in that it had all the detail that the original ones had and this effectively resulted in 4 points of contact and the resulting derailing issues like the HUB cars, a little rework and these also now have no issues when running.

    Hi Chris

    It seems we will just have to check all our Ozzie stuff as you have said. I have just now completed the installation of weathered tarpaulins to my set of 10 Eureka G Wagons to set up W 44, the Concentrate Train.

    No problems with the tarps given all the assistance on platform 1 but before running them decided to do the checks. Sure enough, some with too tight bogie screws others with incorrect wheel spacings and two that just needed a bit more weight. They now perform well and look just like what W 44 should be.

    I have an Auscision Indian Pacific set on order as that will naturally pass through Dargan. Probably made using the same dies as the Aurora. Will look at them carefully for any production faults.

    Cheers

    Richard
