Thank you to all of you for your advice. I’ll get it from its box & check. To be clear - I think you’re suggesting that whilst she has loco drive the pick ups from the track are in the tender. One either side of the centre axle?

It has pickups on the loco and pickups on all 6 tender wheels. In your photo the pickup on the right centre wheel can be seen but not on the left centre wheel which probably means it has been bent out of position and could be jamming the wheel.


If you look at the Hornby service sheet HSS372C item 12 shows the tender bottom plate with 6 pickups sticking up.

Think you find the loco picks up from both loco and tender. you will see connection if you look which has a connection passing power from tender to loco. The more pickups the better for going over points and crossings in particular.

Whoops sorry Brian you already answered. And more clearly than I did I think. When I started writing your reply was not there.

Gentlemen thanks for your guidance. Update: I asked the technicians where I work to help me strip and repair if possible. First off removing tender body we dislodged one wire from the sound chip - weeping and gnashing of teeth followed but techie with young eyes and minute soldering skills resecured. We've also removed the stress from these wires, which are very fine, by securing with hot glue - removing the tender in future will be less stressful!

One pick up appeared missing on centre axle as you all correctly predicted. We manufactured one and soldered it to the bus bar only to discover that the original was bent back hiding underneath! Tender now has seven pick ups! However, I think friction is actually the issue. The brushes seem to cause too much drag (only in the centre axle) which means it is more resistant to rolling than the two others in the tender. It may be a manufacturing thing and I do get the fact that the Railroad Hornby stuff is not expensive. I am tempted to pull the brushes back away from the centre axle leaving the axle to rotate freely and just four pick ups in the tender.

Any thoughts?

I would be tempted to try that next

Just reduce the amount of pressure the pickups exert on the wheel backs. It's better to have as many working pickups as possible for smoothest running.

It may be easier to go to Peter spares you if it is the right one for your tender I looking at (he will tell you) £4.85 a new bottom plate complete with nice new pickups just screw it up and sort out connections.

We did say the missing pickup was probably bent out of the way. As suggested just ease the pressure. The more pickups the better.
