I would endorse that. I'm not sure how the circuitry works though. On mine, if I tilt the trailer coach so that only the wheels on side are in contact with the rails, the lights stay on but dim slightly. Same happens whichever way I tilt the coach. Nevertheless these units are very prone to flickering, with one main cause being the conductive coupling.

There's no bullhead 3-way that's been announced as far as I can see. What you can see listed will be the existing code-75 flat-bottom version.

The lights are organized on the basis that they are directional even though they only show white lights. Hence the two lights in the head code, and you can clearly see when you change direction that all the lights blink. My view is that the head code PCB is not the problem as the interior lights don't work either. The circuitry involves the two feeds with return being via the rails. On the class 411 4-CEP, the interior lights and head codes work independently via F0 and F1: the 2-EPB was supposed to be the same but something went wrong in production! So on the 2-EPB the interior lights and head code are one circuit. On the Kernow Thumper the head codes do switch between red and white, but the interior lights are controlled by a physical switch underneath. My first suggestion would be to look at the conductive coupling to make sure it's not damaged, or possibly fixed the wrong way up. It's all too easily done. Another place to investigate is under the floor on the inner ends of both coaches to make sure the wires there have not become detached.

Have just run a test with a programming track on PQ connection, and everything worked perfectly. No problem reading or writing CVs on the loco I tested which has a Lenz Standard+ decoder. My LZV200 is running a slightly-modified beta software (to enable the PC interface to be used directly with Traincontroller without the +hardware component) and the LH101 has V2.0 software. I quite simply plugged two wires into the PQ plug and connected to a standalone piece of track.

Just seen a post on the Traincontroller website (in German) whereby a user, who's just swapped his LZV100 for an LZV200, reports the exact same problem as you are describing. He says he's only using Lenz decoders and none of them will work. However no response yet, as those who have responded haven't recognized this is a Lenz problem not a TC one. If he gets a resolution I'll update it here. Meanwhile I'll try later today doing a test with the PQ interface on my LZV200. I've never used it since I've always used the Lenz decoder programmer instead.

I got the following response to y query regarding my Gold subscription: "I can confirm this is a print subscription and you should have received the first issue, if you have not, please let us know." The response seems to imply I have a standard subscription not an RM Gold one which I expected to be digital.

When I first purchased the LZV200 earlier this year I found it would not work correctly with occupancy detectors connected on the RS port. I don't know how widespread the problem was other than a number of other people had the same problem. I subsequently returned my LZV200 and only after this did Lenz respond by sending me a replacement to test which works fine. Therefore I wonder if the problem also affects the programming track via the PQ terminals. After all the PQ terminals are part of the same 4-way socket as the RS. I don't use the PQ terminals on mine as I use a Lenz decoder programmer instead. I would suggest contacting Lenz, but perhaps via A&H Models in the first instance.

The OP says the problem occurs with multiple locos with different decoder brands which must eliminate this particular locomotive as being at fault. Is the track clean? Is it fully isolated from the rest of the layout and only connected to the P and Q terminals of the LZV200? My suspicion is that it is a wiring problem with the track somewhere. Does your LH101 have the V2.0 firmware? If so, with the Railcom activated on the LZV200, you can read CV values on the main without using the programming track.

These pickups are designed for fitting to axles where one wheel is live and one insulated. Might need some more work if both wheels are insulated.

And the reverse often happened too. Here's a Black 5 running into East Croydon with a train for Brighton. https://railphotoprints.uk/p883082520/e2e67e045

Indeed football specials often took SR locos northwards. Here's 34054 at Nottingham Victoria in 1963. There were two other specials that day headed by 34102 and 34042. https://railphotoprints.uk/p978695097/e3bb17799 And Railtours were another way, for example here's 35012 at Leeds Holbeck.

The 3-way is definitely Electrofrog - it's described as SL-E99 which confirms this together with the frog wires provided. The 3 other points are all insulfrog as Robert above confirms.

See my post just above for the access info …..

It appears we should have received an email telling us how to access the digital edition but not all of us have. Colin Penfold in the RMWeb Gold forum has posted how to do it. You need to go here - http://www.exacteditions.com/print/britishrailwaymodelling and provide your new subscriber number you were emailed when you first applied, plus your email address and password for future access. Done that now and have access to the digital magazines. You can access them from the link in the RMWeb Gold tab at the top of the screen.

Plugging and unplugging one of these 12-way connectors can be quite difficult. I bought a couple to use as smaller units (eg sliced into 2-, 3- and 4-way) and they're quite tight to unplug just in these small units, let alone a full 12-way. I would suggest considering Nigel's suggestions above.
