I thought, when I bought my 5 car set, i wouldn't worry about the full 14 car train. However, I did, Hattons had the cars on special and i preordered the NDM and when that arrived completed my APT. I had to swap one of the new APT couplers with the old APT. The upshot is it ran well so you are right a full APT needs 2 NDMs. Good video. Cheers

Just what I've been looking for. I sorted my 1980s full length APT out using Eurostar power bogies and would like my new full length APT to run as well. Excellent research and video.

Why is it for paying so much for the APT there is still half hearted work going into the construction from Hornby. Great video as well :)

I like your videos and find them very informative, especially the layout planning ones. The only downside to them is the squealing noise at the end. It scares my dog and she runs away every time she hears it!

That's the sound my DCC booster makes when I turn the layout off. It's a sound I strongly associate with "finishing with the railway", so I found it an appropriate and slightly humorous thing to put at the end of the videos. Perhaps I need to re-think that...

That's very interesting thanks. I found it difficult opening my NDM from 2021 and managed to break quite a few of the plastic clips :( But I see you have had more success than me. I took the expensive way out and bought 2 x R30105 NDM's from the 2023 release. The improvements are immediate: Better traction & weight, 21 pin decoder (easier to fit non-hornby decoders), space for a sugar cube speaker and improved pantograph. Personally this should have all been in the 2021 release from what was already an expensive purchase.

Great video. I have the same spares as you and had the same plan. I also hope to sort out the lighting too (either by through wiring with plug and sockets - ideally to run stuff off potentially just one chip or through sorting the capacitors out) and try and see if any liquid weight can be added to the power cars. The one's include more weight so may source spares from there. I did directly email Hornby about the lack of spares for that part but was met with a digital shoulder shrug. Kinda sums up this model from the manufacturer...

Apparently the APT spare parts have been consistent sellers, so lots of people have had this idea. However, I haven't seen much noise in terms of people achieving the build -- so I suspect there are lots of them in drawers, with people having hit the same problem missing piece! In future I would like to add plug-and-socket connections along the articulated part of the rake, for both pickup continuity and lighting control from the decoder in the driving cab. This should allow the unsightly capacitors to be completely removed from the trailers.

@@FormallyknownasE100 It probably wouldn't have cost them much to ship two identical powered NDMs in the set anyway -- reducing the number of assembly options would likely have saved a significant amount of cost -- maybe enough to offset the cost of a motor, two driveshafts and some gears per dummy NDM.

Are the decoder in the ndms on the same dcc address or in a consist .and did you have to speed match the to decoders
@DongitsModelRailway

They are the same address. While I have tuned the speed (I wanted a scale 155mph at maximum, and a linear throttle response), both decoders have identical settings -- there is no difference in tuning between the NDMs.

Was the coach light flicker the camera or is that what the eye sees? The coach light colours are also different. Seems even with two NDMs it could struggle with the full 14 car set. It’s a disappointing release from Hornby. At least they updated the model on the next release instead of repeating but that doesn’t help those who bought the 2021. Thank you for the useful video.

The coach lights are driven from track power through a physically large but electrically not very large capacitor, and only pick up from two axles each. They do go dark quite frequently as they have been shipped. I have plans for that to connect the pickups through the coaches to address that issue ... but that's a separate project. The lights are not different colours -- the interiors are different colours. They have been made in self-coloured plastic representing the seat colour. Painting the interiors with more detail would reduce this effect. I don't think two powered NDMs would struggle with a full 14 car set -- although I don't have enough cars to build that to demonstrate, this is the maximum length my layout will cope with. I would love to see a 2023 model single NDM tackle a 14 car set on a layout with a helix or similar curved ascent to mine. I'm not buying one just to test it though :D

Does this work with the newer release APT set? R40229A I believe.

I don't have a 2nd run APT (one was enough for me), so I can't confirm exactly what you'd need. However, the general principle should work. There are known differences in the models, so you may need some spare parts specific to the later release. I know the chassis design was modified to add more weight to it, and the electronics are different (it's a 21 pin model, not an 8 pin model).
