Because the car is motoring at that point, it is drawing several

In reality, several thousand. 59 stock and other trains prior to the

that the newer trains draw somewhat more, although being "more
efficient" I
could be wrong..



I seem to remember the 1959 stock motor cars were protected with
600A (or possibly 800A) ribbon fuses. I'd have to dig the diagrams
out to check. I
can't remember with the 85 stock, I'd have to dig around for the
relevant manuals.

Wow, this stuff is amazing!

I thought it was just debris on the rail, but this is a whole new side
of the Underground that I never knew about.

Are there any websites with diagrams of how the power systems on the
various rolling stocks are constructed? Tubeprune has an excelent
section, but it's very general and doesn't give any details about the
rolling stock.


Try here, if you haven't already and follow the many links
