If the centre wheels are on an axle it must need relocating. On tender drive locos the centre wheels were sometimes on little stub axles and wobbled about a lot. Thatís why I asked if the tender contained the moulding for a motor. Hornby used the old tenders with the motor removed when the loco became loco drive.

Thank you wtd. I may try removing tender body first and going in through the top before unscrewing the axles securing plate underneath.

I have a photograph of the insides - not sure if you can add photographs here?

The one on the Hornby website is tender drive. (I can see the cogs just above the wheels on the tender. Also, I know the older versions were tender drive).
This is the 4-4-0 type of GWR county class.

The centre wheels on the tender will have sideways play as part of the design. This is normal for these models. If they are the same as the older versions, they will have the centre axles have play where the wheels can also pivot sideways slightly.
Dont worry. This is part of the design.

Yes, you can add photos here. Will be good just to confirm the model is tender drive...

Thank you Mountain Goat. Iím sure itís loco drive as thereís an electrical connection from the tender through to the locomotive. Iím trying to resize the image to post here.

Take a look just under the tender body. You should see some cogs if it is tender drive. The easiest way to tell is whichever wheels dont freely move when you try to rotate them with your fingers will be the drive wheels.
The tender drives are hidden under an enlarged quantity of coal.
The electrical contact for tender drives uses the wheels on one side of the tender (The other side normally has rubber traction tyres so can't provide an electrical connection), and the connection for the other side goes through to the locomotive part and uses the locomotive wheels via a little electrical connection which doubles up as the tenders mechanical means of connecting the tender to the loco.

It maybe that the new models are loco drive as if they have made the change, won't have any visible black cogs and the four loco drive wheels will not rotate unless they have power applied to them.

I'm intrigued.

Useful to know, thank you. The wobble on my tender drive on my Hornby 4-4-0 was such that I thought the entire works was coming apart, but it otherwise runs quite
decently. No more worries, then.

I’m sure it is loco drive because in a previous post he asks about fitting a sound decoder and the socket was in the tender and mentions it is loco driven. Surely the old tender drive version wouldn’t have been DCC ready.

Well if it is the loco drive tender I pull out of this one because other than build up of fluff or dirt or it is wedged somehow I can't think what else can make it stiff. All those things have been suggested. Is it one of those tenders with the bronze pick up and a pick up may have got bent up somehow. Can't think how though.
