Right around the time when I usually get out of work, I received an alert that there were delays on the subway line I take to go home due to signal problems. In a previous post I stated that I almost always get these type of alerts when it's too late. Well, today was one of this rare times I received it just in the nick of time.
Some delays you know it's best to think of an alternate route because of the nature of the delay. This one though is one of the more vague ones. A signal problem could mean that trains have to pass through that troubled area slowly and hope they don't trip the brakes. It could also mean that a particular signal is malfunctioning, staying red the whole time and train operators have to override it somehow and pass by it at a snail's pace. So as you can see, the degree of severity of the signal problem is so vast that it can mean either a couple of minutes delay or standing on a platform for half an hour.
I took my chances with this delay and stuck with my original route. It turned out not to be a big deal. In fact, time-wise it felt like the normal commute home. Whew, I got lucky this time!
