Scheduling to do work on the subway system must be quite a logistics nightmare. I get it, I really do. But is it really necessary to have almost every single line in the system under some kind of closure or detour AT THE SAME TIME? One of the advantages of a vast system is that if one line is closed there are always others than should be running normally. Of course the problems multiply the farther you have to go with this kind of massive upheaval. It was a bit of a mess getting to and from upper Manhattan tonight. Are there improvements being made to these tracks or lines? Repairs? Staffing problems at these segments? A master sadist behind it all making ice cold commuters jump through hoops for his (or her) sick amusement? I haven’t lived in NYC in many years, but I don’t remember ever having such a large number of train route service advisories in all the time I lived here or during my many visits. Is it my imagination or is this excessive? Is this (gasp) normal?
