Thanks Cal I got that much... you'll have to forgive my lack of knowledge. While a dedicated rail rider, I'm not in the category of fans who understand many of the elements that go into the rail operating systems. For example, you will never hear me wax eloquent on engines as so many do. My appreciation of the engines extends to if they work.
Back to those signals. What signals are these exactly? Why would they take 8 hours to repair? How often does this happen?Is there no workaround? 8 hour delay on a corridor train that normally takes 6 hours from end to end is worth trying to understand a little bit more about.
