The Oslo T-Bane has been a mess for about two weeks now. Trains have been running off schedule and at reduced speed and capacity. Line 3, which I take to work, has service completely stopped west of downtown and replaced with buses.

There's apparently some kind of problem with the converters used to electrify the 750V DC third rail. The other day going home, the driver came on and said we were driving at a reduced speed because of a low voltage, but I couldn't pay much attention because I was about to throw up from the jerking back and forth.
