The one IP 4 wheeler I have completed was also prone to rocking, and derailing on any track with imperfections in levels ( subsidence, uneven camber - not on my line, obviously ).IanC wrote: ↑Thu Jul 19, 2018 10:24 pmThank you Phil. Funnily enough these got done before my two IP four wheelers, even though I got the four wheelers first. I have to tweak one of them a little as it rocks abit when test run, either because the wooden solebars have twisted or my poor workmanship.
My plan was to have two rakes of coaches. One for larger lines, which are these Newqidas, and a rake of four wheelers for small railways. The rake of four wheelers will be my next project. I will probably sell the IP coaches as they are no longer in production and I can't get any more to match them. Still considering which ones to go for. Swift Sixteen are favourites at the moment.

I cured this by removing one of the solebars and refixing it 'hinged' in the middle along its length (a pivot point, if you will) and then trimming a little from the top edge at each end. With the axleboxes fixed to the solebars, this allows it to compensate for uneven track, and it has run well since. It wasn't my idea, but I can't remember where I got the idea from
