What I am interested in though is something really easy to P4-ize a RTR wagon
Masokits do a fret for just this purpose, and if you do only one axle per wagon you will get twice as many for your money, and if you find problems with that you can always do the other axle later.
Thanks for the idea Keith. So far I haven't had any luck with the Society link to the Masokits catalogue.
My first post on this Forum at viewtopic.php?f=23&t=693
was on the very same subject. The thread there got hijacked by a debate about the heresy of using EM wheels as Will mentioned earlier today, but I don't think much has changed these last seven years.
Since then I have completely proved to my satisfaction that MJT wagon compensation works, with adequate weight. I don't want to tempt fate nor sound overly boastful but as far as I know none of my my so equipped wagons have ever once derailed at an exhibition, unless for example a point has not thrown properly or some very obvious track fault has happened. Why I ask if there is an even easier way is that people seem so keen to persuade me that rigid will do because there isn't time to convert everything - yet people are happy to spend what surely must be at least as much time on elaborate weathering or other cosmetic work. Were I to get into the groove, I would think that the time taken to install the MJT inside bearing even in my elaborate way would be less than a morning's work.
I just think that the only acceptable standard for derailments (in a Society that professes to "Get It All Right") is zero, in the same way as Tony Wright said in the Snooze, some while back, is his standard.
I also readily admit that to have compensation or suspension of some sort applied to any vehicle doesn't mean it's not going to derail. It depends on whether the design and/or execution of that design is adequate, and I agree that a rigid vehicle is going to behave better than one with a poorly installed or designed suspension.
Anyway as Allan said, to divert the subject to wagon suspension is not sticking to the thread.
So to get back on topic here are two more videos (very short because I didn't have much space on my phone) of the Barclay Tank I showed earlier careering round an impossible reverse curve. Now it's finished except for a rather iffy paint job and here it is drifting over the 3 way of the Calderside Exchange Sidings that also got their first outing last weekend at Glasgow's Model Rail Scotland. It is equipped with a Flexichas suspension, with two longitudinal beams between the rear two axles and a rocking front axle, the rear beams optimized for roadholding as per my Snooze first article. It did not derail once this first weekend of revenue earning service, and again I don't like to boast but have to say that none of my stock derails despite some slightly iffy trackwork in some places on the layout that does catch other stock out, unless something goes out of adjustment like the B2B or a loose tyre.
