How Does A.W.S work?

Depends how far to the red signal but nearly all UK railway companies set down maximum speeds at what they want there drivers to be doing when they pass over the AWS magnet before a red . most freight is 10mph , most passengers 15mph :)

cheerz, someone told me that if the next sig was set to danger drivers did half the normal speed, so if they were doing 50 they did 25.:hehe:

Half speed at yellow

MSTS signal instructions tell us that a yellow signal means half speed, because the next signal after that is red. Out in open country with good visual command of what is ahead, that is probably reasonable over a long block, but you still need to be able to come to a complete stop in front of a red signal when you get there. Even 10 or 15 mph may not be slow enough if your train is long and heavy and you're on a downgrade when AWS gives you only 200 yards notice. I'd think the speed over the AWS would depend on the engineer's familiarity with his load, his equipment, and the terrain. For us amateur railroaders using Trainz, that may mean several tries to figure it out for a given situation.

On our railroad, a yellow(approach) signal means begin reduction to medium speed(30mph) as soon as you past the signal, prepared to stop at the next signal. The next signal could be 4 or 5 miles away or it could be less than a mile. This is where being qualified on your territory comes in.

Thanks for the info:)

With Driver Reminder Appliance. Wiki says that drivers apply it when stopped at a red signal or when then get out of the cab, so it disables the throttle.
But what i want to know is... do they apply it when stopped at a station? and if there is any other times it gets used?

AWS and british signalling practice is different to US pratice. When you (the US) see a caution signal, you have to reduce your speed to 40mph (IIRC). However, in the BR Rulebook, there is no limit to how fast you can approach a caution signal, but the best pratice is to slow down after the signal.

TPWS however, requires you to be under 40mph on the appoach side to a danger signal, before the emergency brakes are applied.

EDIT: Voyager, DRA is to quote someone I know, a device that good drivers will use and bad drivers won't. The idea of DRA is when the driver comes to a stand at a station, the driver will manually set the DRA as soon as he comes to a stop (or open the doors). All DRA will do is as you say, disable the power handle, but s/he can still operate the brakes. However, when the signal changes to an aspect other than danger, DRA isn't normally required to be set, since its only a safeguard to a SPAD.

Thanks;) so what your saying is. the driver stops at danger aspect or station, dra is manually applied. then taken off when aspect changes to Caution/Clear or departing station . driver takes dra off.

i have seen S.P.A.D. triggers and signals in my stuff on trainz. could you tell me how to set it up or how its works?

IF you mean SPAD signals, they are totally different, they have 3 red lights, the top and bottom one flashes, while the centre one is solid if a driver commits a SPAD. The centre one (I think) also has STOP in the centre as well.

As for the signals, depends if you got snowsignals ones, there are no freeware ones yet (AFAIKO).
