Info on converting a P4 conversion back

Replace the wheels. A decent hobby shop can sell you the spares you need.

If the loco has had equalisation added, leave it alone. It much improves tracking and traction.

Could be anything, depends on the loco in question and the person who converted it.

It might just have some replacement wheels. In which case, you need the original ones to put back.

It might have some other modifications, such as the brake gear moved / changed, which may get in the way of refitting the original wheels.

It might have a whole new mechanism. In which case you may or may not be able to fit it with OO wheels, depending on the space available.

If it's steam and has outside motion, it would be more difficult than just replacing the wheels, although I suppose bringing the steam chest/cylinders and valve gear hangers that 2.23 mm closer together may be easily reversible.

Thanks all

Ok it has become patently obvious that this may be a pretty involved job - I am wondering why replacing the wheel and not the wider axles has been the advice. Important to state here to anyone who doesn't already know, that I am a returning hobbyist and had never heard of EMs and P4s until this year. I will Google up some further information so I can approach this more efficiently.

The loco is an old Triang Caledonian Single - no motion

Oh 'eck! You don't just pop down to East Kent Models and get spare wheels for that! Axle sizes are likely to be odd as well, I would guess. Personally, I would be mighty glad to have one of those in P4, because it would save me the hassle of converting it from OO :-)

Hi Paul

I ended up with a Lord of the Isles in P4 not a Caledonian. My error. Same chassis - different bodies. I actually bought it with a view to converting it back, but believe it may not be worth it so if you're after a P4 Lord of the Isles (or Dean Single as it is correctly titled) let me know as I will be on-selling it probably.
