I've heard some wonderful stories of the AC getting mixed up with the
DC or the high voltage getting mixed up with the low voltage and the
circuit breakers going ker bang. In spite of the exemplary job they
do, mistakes do happen in Europe. But I am still amazed that they
run trains from country to country to country and mix three or four
of five voltages and frequencies and sometimes the only thing that
suffers is an inability to have food service until they get to the
border and can use the stoves.
I am most amazed at the ability today to use lightweight technology
with high voltage alternating current. We had 6600 volt AC
interurban cars in 1907 and most of those systems lasted only a few
years. The Washington, Baltimore and Annapolis was probably the
best know and it only lasted something like 18 months before
conversion to 1200 volts DC. Those AC systems were horribly
impractical because the cars weighed so much. However, today we can
build high voltage AC / low voltage DC streetcars and think nothing
of it. They are running in both in Karlsruhe and in Saarbrucken,
Germany. Run them over city streets downtown and then over the
national railroad system as commuter trains. And they don't get
agitated with buff strength requirement like or FRA does. They mix
trolleys and 150 mph trains on the same tracks! I remember reading
that when Saarbrucken received their cars, they simply left the
factory with a train crew and were run over the Deutschebahn under AC
to Saarbrucken and put in service. By the time they got there, they
were broken in!
Bob, we've got to take some of these other people over there and show
them how the rest of the world does it!
