I am no expert on LZB/PZB or the ICE-T, but I have a question about it in relation to the Frankfurt line. Both LZB/PZB are on, LZB is available at the start of the line at Fulda, and for about 20 km towards Frankfurt, but outside of this PZB is active. During (my) runs, I don't get any indication from the 1000 hz or 500 hz magnets because none of the signals require it, I do however get an audible warning for speed limits, and a solid "G" that responds to me slowing down by turning into a flashing "G", which will only extinguish if I go (significantly) under the posted speed limit. Is this correct operation?, is it a result of the increased speed of the train due to GNT?, are the speed limits listed on the HUD "tape" speed limits from the GNT, rather than the line? I also seem to have an issue (which is also reflected on the WCML) where the train(s) will do uncommanded braking at the end of the run which means I can't hit the final marker as the game cuts out the throttle and just keeps applying the brakes, is there some kind of anti-SPAD protection going on in the game? or am I just, after all these years, doing things wrong!.
If you have the safety systems on and you approach the platforms or a signal too fast, the emergency braking will apply (TPWS). You need to be under a certain speed before the buffers at Euston or the red signal at the end of the platform at Milton Keynes (or any other red signal in the UK). It most certainly is an anti-SPAD device and a safety device. As for the German one, I don't have much idea about PZB, LZB, GNT etc
The weird part is, it's not something I ever experienced in previous iterations of the sim, despite similar setups, I am doing (very) slow speeds when said braking occurs, so I don't think it's TPWS.
TPWS has been simulated in TSW for a long time. Are you sure it isn't TPWS? That's the only thing that would cause emergency braking apart from not responding to the DSD beeps within 5-7 seconds. You will know you have triggered it by a red light on the TPWS panel. Once it has been activated and the brakes applied, the brakes cannot be released and power applied for 45 - 60 seconds I believe.
That's GNT supervising the higher speed limits for tilting trains. Solid G means that you're approaching the brake curve for a lower speed limit; flashing G means you're in the brake curve. You don't need to do anything (other than brake in time for, and stay below, speed limits). The speeds shown on the HUD are the correct ones for a tilting train.
As for the Frankfurt-Fulda route, there seems to be LZB brake curve being generated to the scenario marker (at least on some services ending at Fulda), so the LZB will force you to gradually slow down to 0 km/h at the point of scenario marker. This is a bug, the curve should be generated only to the signal that is behind that marker.
Thank you! I've got the hang of everything else, but I couldn't for the life of me find any explanation for the flashing G and why it wasn't going away when I'm already at a lower speed than I'm supposed to be – because it's effectively telling me that I've already reached the right speed?
It doesn't take into account how close you are to the target speed at all (as long as you remain below it). I meant being "in the brake curve" in a location sense: if the lower speed limit starts at km 12,7, and the latest point where you can apply the brakes to reliably get below the upcoming speed limit in time from the current speed limit is, at km 12,2, then you'll always get the flashing G between km 12,2 and 12,7 (and the steady G for a while before 12,2), no matter what speed you are going.
