So i guess it only makes sense to use DC electrification on lines with frequent service.Not only due to low ridership which doesn't call for electrification, but to protect the signals as well, from this vulnerability due to rusty nails. But my question is why not make BOTH running rails part of the return circuit? The AC shouldn't be affected, and it is easy to filter out DC signals with a capacitor, isn't it. But you would need a BIG one. |
