Was reading the newswire and saw an item that Amtrak got tangled in overhead wires.
I live where the only wires we have are telephone wires along the train tracks.
Does the entire east/northeast have overhead wires? Our Amtrak doesn’t use them, but obviously does in the NEC?
Why?
Jen, Mookie, Mook, Madam Da Mook - testing these to see which one you like.[}:)]
Well the answer is that cities started to require railroads in the NE to cut down emissions from locomotives.there are also alot of tunnels that go through or and under cities too. they are not all wired though.Some tracks pick up the current form a third rail in the track too.The most famous electric engines that ran along the ne corridor are the pennsylvanias gg1’s. hope this helps Maam.

The term for the wires is catenary. The locomotives under them cannot (FL-9’s et. al. excepted) run unless connected to the wires as there is no prime mover (diesel) to provide electricity to the traction motors that drive the wheels. The electric wire catenary system is very expensive to build initially, but has economies once the system is running including the fact that the locomotive running downhil or during power braking generates electricity and puts the power back into the wires. Electric locomotives also tend to be horribly expensive compared to diesel engines.
really, i thought they would be less expensive due to the lack of a prime mover , main and aux. gen’s.
Eeeeeeddddddyyyyyy! It’s your turn to watch Madame Da Mook this weekend.
I vote for Jenny.
catenary makes zero sense when you have two ribbons of steel already goin the same route.
