SEPTA’s best job? Or SEPTA’s worst job?

I took the 100–ahem, the Norristown High Speed Line line–the other day, and noticed this dude just past the Bryn Mawr station.  Apparently, he’s been there quite some time due to the ongoing track work.

According to a friend who rides this line pretty regularly, he just sits there, day in, day out, attending to the stop sign.  A vital job, no doubt.

My question, though, is this:  is this SEPTA’s best job?  Or SEPTA’s worst job?
