yup, back to the old school coach today, and I'm gonna be stiff tomorrow!
This bus threw its left pole every time it switched through the 3/James switch. I inspected the shoe and found it cracked, and requested a replacement shoe. This done, but no real help.
At one point I tossed my bag in the space behind the seat and hit the fire extinguisher by mistake. This shouldn't be a problem, but there was no pin in the extinguisher. POOF, a cloud of yellow powder. sigh.
