Atomic Systems

I am running an activity for the Thames Mersey with a class 87 003. Just about every time I pass a signal this damn alarm bell rings in the cab. What, pray tell, does this mean?

That'll be the AWS... It'll ring every time you pass a clear aspect, then (in real life, not in MSTS) when you pass a caution/stop aspect, you will have to press a button to stop the bell as a safety precaution or the emergency brakes will apply...

Bell for clear signal. Any other aspect sounds a loud and annoying horn, which has to be cancelled.

Do those systems exist in North America too?

Matt,

Some railroads here have a version of Automatic Train Stop and cab signals. The NEC is a good example. As far as a warning sound, I am not sure. Most engines in North America have the alerter, but that is more for crew safety then signals.

I had always believed that a bell signal ( = clear signal ahead ), did not have to be acknowledged, a horn ( = signal ahead at danger ), has to be acknowledged to avoid automatic brake application.

That's right - a bell rings for a green signal only, which does not need to be acknowledged. Any other signal or advance warning board will cause a horn to sound, which must be acknowledged.

Geez, I'm learing so much more here than I ever thought!

That's before we get into TPWS and the like...

Sam

TPWS? Something else to do with signalling, or something else?

Just be grateful you dont get the driver alerter that acts as a dead mans device, that a lot of modernish EMU's have now thats really annoying!
