Amtrak 501 Derail in Washington State

If I am correct PTC will NOT stop slow speed (>20 mph) accidents. So if an engineer slows to 15 mph and doesn’t STOP at a STOP & STAY (Home) signal, will PTC initiate a penalty application and prevent a potential accident if there is a train in the block ahead of it?

Nothing can go wrong…

If PTC is active it will enforce (stop) you at a stop signal if you are going 100 or 1 and don’t stop on your own.

But if you are coming into a terminal with a track that stops at a bumper post, will it keep you from hitting the post at 15 mph?

You could set up a stop signal/0 speed at the bumper, then it would. Otherwise, you have to follow restricted speed rules.

Automation addiction will result in more disasters.

Well the bypass was to begin operation on the 18th - it is now the 22nd and I haven’t heard of any major derailments.

OOPS double post

This poster is worrried that PTC that the freight RRs have will not last due to GPS problems. The more expensive Amtrak ACSES probably will survive.
