I was driving an HST on the Newcastle to York route, and it was on the stretch between Thirsk and York I had hit 125mph but triangular sign kept come on indicating I was going faster than the line speed, I was travelling at 125mph with throttle on max power.

If I'd pushed it to 126mph I would expect to see it. I returned the power controller to the off position and it still stayed on.

Is this a possible bug?

Yes, I get that as well. I just ignore it and report it as a fault when I get back to the depot. Unfortunately, the fitters never seem to fix it

A mischevious - and technically correct fitter might suggest if the maximum speed is 125mph then at 125.1 mph you are exceedumg the speed limit
Or am I just being that fitter?

Yeah it probably is a bug...

I've noticed that there can be a significant discrepancy between the HUD speed display and the F5 speed display (which always reads to 0.1 mph IIRC).

Which one are you looking at?

It happened to me as well. As soon as the speed hit 125.1mph (according to the F5 display) the red triangle shows. I did a few runs from Reading to Paddington last night, and the evaluation at the end says that the speed limit was exceeded for a certain time and distance, and that the limit was 124mph! I think at lower speeds there is more allowance for overspeed.

I've also noticed some strange speedo behaviour on Cajon Pass with the mile long consists. The cab speedo, F4, and F5 all show different speeds when setting off.

Has it on HUD. But I will look at F5 next time I play it.

I'm pretty sure I've read somewhere that the speed shown in the HUD is that of the rear of the train, so on long trains you will (and should) see a difference at times.

OUCH! I didn't know that. I've always assumed that the HUD speed was what the driving engine was doing (indeed, it probably should be as TrackIR isn't around to help me glance at the 3D in-cab speedo). That would explain the wild speed swings in pre-TS2013 days when pulling one of those huge US consists... Made all the interesting US scenarios pretty well unplayable on my system. Haven't noticed it on Sherman Hill thus far though...

Straying a little further from the topic I think the gradient value shown in the HUD is that experienced by the last vehicle of the consist as well.

Another possible HST bug, I've noticed that I'm only getting one tone on the horn. Anyone else getting this? Not sure if it's something wrong on my installation but I'm loathe to do a verify cache as I don't have the time nor the inclination to have to re-install dozens of AP soundpacks etc again!

If you've put on the AP HST sounds (any pack), then I'll bet you're running a repainted HST that hasn't had it's bin file updated for the two-tone experience. There are instructions with the HST Combo pack 2 (which I have) that tell you how to edit the file to achieve the two-tone effect, the instrructions may well be in all the other AP HST sound packs. You just need to find out which loco it is and then apply the fix using RW_Tools or another similar bin file editor.

Increasing stiffness and damping on the couplers makes that a lot more manageable.

Yes, I think you're right there. Explains a comment someone had a while ago about their train gaining speed (at zero throttle) on a "level" section of track...
