Why were the Underground trains cancelled?

Question

Doh! They are underground and shouldn't have been affected.

The DLR is still running, and they are above ground.

Answer 1

The majority of the Underground is, in fact, above ground. Pretty much all of it outside of Zone 1 is uncovered.



Delays on part of a line (or indeed any lines that share track) can have awful knock-on effects, which is why the Circle, H&C, and Met often go down together.



There are only so many places on the network for trains to turn around too, so the suspensions will always be to those stations.



Staff have to be able to get in to work - we have staff locally who travel from one side of town to another, or even further. Each station has to have so many staff in place to open safely. Each train needs a driver.



There's lots of reasons why the weather affects the Underground.

Answer 2

I live in NJ, and its hard to imagine the railroad shutting down with only 8" of snow.



I guess when you're not used to it, its better to be safe than sorry, but the trains can run in that small amount of snow, its not really a problem, they do here all of the time. We get that amount of snow at least once each year.



Someone is being "over cautious" and doesn't want to be responsible if anything happens, which it probably won't.

Answer 3

55% of the "Underground" is above ground

Answer 4

i believe its got something to do with the third rail power supply. you could get shorts what with the water and electricity.
