Any list of lines that are electric or diesel?


Recommended Posts

Yes many diesel trains run under wires due to the unwired lines being in rural areas and the main stations being in the wired city or more developed area.  You'd need to be more specific as that are so many across Japan.  Typing them all out would take some time.

The basic rule is to look for diesel lines that join electrified mainlines near their terminus or diesel lines that are part electricified, usually on their suburban parts. In the first case, the diesels have to enter the terminus, so many times, they do this by going under the overhead wires if there is no dedicated diesel only part of the station. In the second case, the line might be split between diesel and electric parts with a change point at the last electrified station or some diesel services might run all the way from terminus to terminus.

This is extremely common in Kyushu, as while main lines are electrified most smaller lines are not, so even though many services share much of the route with the electrified section, if any parts use a non-electrified line then the whole train must be diesel powered.  JR Kyushu has actually just begun experimenting with electric trains equipped with batteries to try to cut down on this happening, by allowing said EMUs to run under over head power when able, and to use stored onboard power when not.

The same applies on Hokkaido which uses a lot of loco hauled trains, of necessity diesel hauled. The same with multiple units the majority of which are diesel powered because outside of Sapporo only the main lines are electrified. Even the mainline from Sapporo to Hakodate is not wired between Higashi Muroran and Goryokaku.

Are you talking about diesel loco-hauled freight trains in Hokkaido? Those indeed run long distances under the wires, especially between Higashi-Muroran and Sapporo. JR Hokkaido also uses DMUs on the local passenger service between Tomakomai and Higashi-Muroran, but this is more of provisional solution to the fact that there are no 1/2-car EMUs available. Then there are also limited express DMUs that run along certain electrified sections around Sapporo. The latter also happens with plenty of other limited expresses around Japan, such as the Nanpu, Hokuto, Hamakaze, etc. Furthermore, local DMUs running along short sections of electrified tracks is simply extremely abundant all over Japan.

Oh, I just thought maybe someone had already made a list since the actual lines are all listed on wikipedia.
