Replacement wheels for Caledonian Sleeper Coaches

[Skier]

Hi All

I have a set of R2663 Mk3 Caledonian Sleeper Coaches in First ScotRail livery.

I want to change the wheels but am not sure what size to get. Would anybody be able to advise please?

Many thanks

The tooling for this vehicle was inherited from Lima, who used shorter axles than Hornby.

So, if Lima bogies were used, while the wheels are almost certainly 12.6mm diameter, the wheelsets in pack R8096 may have axles that are just a little too long so that the pin-point ends bind in the axleboxes.

Unless someone who has changed the wheelsets on this vehicle and can confirm which new wheelsets were used, I would suggest you contact Hornby Customer Services for advice.

Have a look at peter's spares, or contact Hornby support. I believe that the coach in the GWR HST Set uses the same wheels, you may be able to obtain them from there.

Hi

Thank you so much for your replies. These are really helpful.

Principal reason for looking to change the wheels is because the coaches are derailing on a set of Hornby Express points set to curved. These are the only pieces of rolling stock on my layout that will not pass over this particular point. From watching closely the wheels are riding up onto the nose of the point and are then derailing - it appears to be the flange that is causing the issue.

I have checked and adjusted the back to back measurement using a Gaugemaster gauge but this seems to have made little difference hence the idea of changing the wheels.

The phenomenon may well be indicative of Lima wheelsets as their wheels tended to have deeper flanges. (Wheels should be set to 14.5mm b-t-b to run through Hornby pointwork.) Check with Hornby re suitable replacements.

Try reducing the back to back distance, older, coarser wheels may need reducing as low as 13.9mm. As you have the gauging tool, it should be simple to reset them to 14.5mm if needed.

Sam'sTrains has done a video on this exact subject, there is a link down below.

Hope this helps.

Hi All

Thank you again for your continued input on this.

I had actually seen the video from Sam - this gave me the idea to check the back to back measurements.

I have dropped a note out to Hornby to see what they suggest and I will report back once I've heard from them in case someone else has the same issues.

Regards
