Pendolino woes

[Newportnobby]

Could it be something as simple as back-to-backs on the Pendo?

Sorry to ask nobby but what are back to backs??!

It's, as Nick says, the distance between the inner flanges of wheels. This will help show what I meant......

Thanks and appreciated @njee20

The tolerances do appear miniscule. I'm running on Kato track with a gentle wide radius but still get derailments that I didn't have when first purchased, only after "repair" that put the traction tyres back on (as well as reinstalling the DCC/Sound)

Also I appreciate the push/pull may be a factor but I have other HST's with a two motorised cars that don't derail like this.

[By the way @njee20 I saw elsewhere that you design waterslides for liveries. In the long term, after getting the basics working I might want to convert my Pendo from Virgin to Avanti livery, same with my two Dapol Voyagers. Do you have a link to where you sell them or was it just a personal project?]

The experience of reinstalling the traction tyres mimics mine - the train ran far better without them, even just leaving the grooved wheels. That's just not an option for me on code 40 track.

Must be a very old Poole Farish HST to have two power cars? Much easier to only have one, mitigates all of this!

I do sell the decal sets, the Avanti ones for the 805 (using a Kato 800) are on eBay. Problem is that they take a lot of effort, and as there's a Revolution Pendolino (and Dapol Voyager) in Avanti I haven't done those ones. I'm just finishing off the climate change and Avanti pride Pendolino sets though, but they'd need a lot of repainting from an original Virgin donor model.
