Seems like a easy way for Republicans to kill Amtrak.
Just don't give the extension!
Ofcourse Railroad Retirement will that a huge hit for unemployment.
How many workers will be effected on all railroad?

If you have a scanner or access to railroad radio channels try and count how many times you hear a train crew call a dispatcher concerning PTC issues.
It goes like this:
DS this is Train #123 over.
DS answering 123 over
DS PTC fails to initialize over.
123 cut it out and run without time 1355 ABC over.
123 understands cut PTC out and run without, 1355 Alpha Brovo Charley over.
That a good repeat out.

How. Many times do you have issues with your computer.
Remember the government mandated this technology for a failsafe system!
