In the Pendolino cab in Train Simulator 2021 there is a flashing red light that is labelled “TASS” to the right hand side of the driver. Can someone please tell me what it means, thanks?
TASS means Tilt Authorisation and Speed Supervision. As fabristunt said this is the Train Sim World forum, and since we do not have that train yet we can provide limited help. You will probably have more luck in the Train Simulator forum.
As usual, the answer with TSC queries is "read the manual"... https://cdn.akamai.steamstatic.com/...lass_390_Pendolino_Manual_EN.pdf?t=1575656047 2.6 TASS (Tilt Authorisation and Speed Supervision) The Tilt Authorization and Speed Supervision (TASS) system features balises located in the track which provide information to the on-board computers, telling the train when it is authorized to tilt and the maximum speed that the Class 390 can operate on that particular stretch of track. For the sake of simplicity in TS2018 the system is done automatically and no balises are required or present, with braking curves for speed changes being generated automatically. In essence, TASS operates as a form of speed monitoring, being a more sophisticated version of the earlier C-APT system found on the APT-P. The system works in the background and should you drive the route correctly TASS will never intervene. The basic functions of TASS are as follows. TASS demand light extinguished, no alarm sounding – Normal operation, speed in normal ranges. TASS demand light flashing, alarm sounding – speed exceeded track limit, or braking curve by 3.5mph. Alarm cannot be cancelled, will automatically cease once speed dropped to correct range. TASS demand light steady, no alarm sounding – Speed exceeded track limit or braking curve by 6mph. Emergency brake application actuated. Emergency application cannot be cancelled at this stage. TASS demand light flashing, no alarm sounding – Speed returned to normal levels by TASS demand application, emergency application can be cancelled by pressing the Q key or the intervention reset button, otherwise train will be brought to a halt. The Braking curves for the TASS system have been calculated at a deceleration rate of 0.88ms-2 which is approximately equal to step 4. Should you exceed the braking curve and get a TASS alarm you will need to select Step 5 or 6 in order to correctly meet the upcoming speed limit.
