This thread is now locked in order to prevent further speculation. R-

Thanks, just to be on the safe side we will pass that to George now. R-

That looks great, well done. R-

That’s ok, the main points were there perfectly explained. R-

Hi @DuTTchy, how did you manage to cut the bulkhead of the cab away so neatly? Also, I think you are showing Insulfrog points in your video not Unifrog. I can change it for you if you like. R-

Struggling a bit to find a suitable non-conductive material to fashion into a washer. R-

As reported in this thread [where I will continue this conversation] the loco is now quieter over points, but the inner wheels still lift on curves. R-

The b2b adjustment has certainly quietened down traversing points. However the inner wheels of the bogie are still lifting on curved track. Time for the @David-370477 washer treatment. R-

We’ll see, it seems more challenging tbf. I have made an adjustment to 10.4. I’ll report back tomorrow. R-

Thanks all. I have just re-measured and the b2b is definitely 10.2. I imagine the safest way to adjust would be to remove the bogie? Just to be clear I am using Hornby track.

Right, so the tiny screw at the back of the arm. Yes, tight and arm straight. R-

If you mean A it looks like Hornby have replaced the black tape on a screw that looks as though it is fully home. Or did you mean B?

I think the bend up/down procedure is what they did last repair, when I got frequent derailments on R3 curves. It is odd that they always sign off the job with “ tested - ok “. R-

IMG_1864.mov Front bogie is awry somehow, not sure what is causing this but I think the adjustment Hornby have made has caused a further problem. This is on a R4 curve and the front bogie can be seen to lift and make contact with the first driving wheel, only visible from inner rail. On R3 that causes a derailment. On R4 it clicks back down after a few seconds and off it goes for another circuit. I can see nothing wrong with the track and there is nothing caught on the underframe. R- Edit: no adjustment has been made to any b2b.

Yes, inside back of flanges. There is a noticeable “clatter” going through points, but the bouncing and eventual derailment is on a R3 curve. I think from what you’re saying I should try to ease the wheels together a tad. R-

My Silver King has just returned from the menders [Hornby] as it was constantly derailing and apparently needed the front bogie bracket to be adjusted. Running this morning on an R3 curve [previously problematic] it ran perfectly for about 6 circuits and then I noticed that the bogie wheels where lifting and falling - giving the appearance of a slow bounce - before leaving the track. I am using Hornby track, so confirm the 12.1 inner rail measurement but it looks as though the b2b is a bit out. This looks to me to be 10.2. Am I reading that correctly?

Do you get any error codes? R-

Ditto. R-

Kapton tape. R-

That’s fine. You are not expressing a negative opinion. R-

Tare weight is unladen weight. R-

Yup, I can find this The HM7070 Power Bank will keep locomotives running over any potential dead spots. It works in a similar way to 'stay alive' or capacitors which are available from other manufacturers. And this (The Power Bank is not suitable for use without an HM7000 decoder, connecting it directly to other decoders or directly to the wiring of a model locomotive may cause damage to the Power Bank) Nothing about being especially designed though. R-

Where does it say that the Hornby Power Bank was especially designed for HM7000 decoders please? R-

@ateshci - good find there and a valuable resource. Unless and until a knowledge base [or similar] comes along could you put them both in either your album or the general album? R-
