Is the brake rigging fitted? If so is there clearance between it and the rails? Many years ago when Dapol brought out the B1 I saw one that was more of a sledge than a loco. Derailed on points, and the rigging caught in the sleepers going backwards. Removing the rigging removed the problem.

£0.484 for a pack of 100 excluding VAT and postage from Rapid Electronics. As Iain said 0603 sized. https://www.rapidonline.com/10k-0603-1-1-10w-royal-ohm-chip-resistor-pack-of-100-72-9849 I've used Rapid Electronics for years, both for work and personal use. Never had any issues, and they live up to their name!

It looks like a Poole developed loco that was put back into production in China without any changes. Pickups are on the three main drive wheels each side. No traction tyres - the cast metal body and chassis provided all the traction.

Look at the one edge-on. It's the 3d ear!

Correct, but I didn't have the time to change it #i didn't create the meme

Essential modelling advice....

Surely "WHERE CHILDREN AND LEARNING COME JOINT FIRST"

The Lima 20 always had a can motor driving one bogie through a cardan shaft. The body was too narrow to accommodate the pancake motor bogie. Still not a great runner though.

The spokes are definitely metal. Since moving away from the split chassis mechanisms their steam locos no longer use the plastic wheel facings that swell up and buckle causing the locos to waddle.

What software version is the decoder - in the red box in Paul's screen grab it says "ATTENTION: DC analogue operation only implemented from SW version 4.50"

View Advert Chassis castings for Hornby Scot / Patriot These are the castings to replace Mazak rot in the Hornby fully detailed Royal Scot and Patriot models. You'll need to re-use the rear stamped metal motor retainer, wheels, pickups and all valve gear. Screws are not included, and I believe the screw threads in this casting differ from the original. UK sales only as their price includes postage. If you let me know your email address I'll send a Paypal invoice for payment. Advertiser Tim123 Date 31/05/23 Price £25 Category OO / 4mm scale  

I bought my CD motors as conversion kits, each came complete with a 3D printed cradle and the correct gear. I've done several Hornby and Lima models, each one has been a big improvement. Lima DMUs, 47s and 37s crawl silently round the track, aided by Zimo MX600Rs with around 8000uF stay alives.

He still shows them as being in stock https://www.petersspares.com/p/peters-spares-ps13-nylon-screws-for-Hornby-ringfield-dcc-conversions-pack-of-10 Fitting a CD motor will give a big improvement in running, and they are electrically insulated from the casing. Some are only rated at 6 volts, but if you use a decoder which limits the voltage, such as Zimo with CV57, then there will be no issues with motor burn-outs. Quite a few guides on the likes of YouTube.

There will be a thermal cut-out in the controller. It will trip out if there’s a short circuit, and auto reset a few moments after the short has been removed. Assuming all you did was remove and dismantle the motor then I’d check that the insulating sleeve is properly located on the brush retaining spring, as shown on the service sheet. Also check the carbon brush is correctly seated and not touching the front of the motor housing. Same applies to the suppression capacitor, one end is screwed to the chassis block, the wire coming out of the other end might be touching the motor too.

Son, let's set up the Hornby Family Fun project. And if you're really good we can put a loco and some rolling stock on the track!
