Track versus train

I have removed the section beginning: "The building of the Channel Tunnel between England and France required triple electrification of the motive power..." This is not relevant to double electrification of the track. Biscuittin (talk) 18:41, 8 June 2012 (UTC)[reply]

Dual Electrification

The term "double electrification" is one that I have never come across in over 20 years of designing electric traction systems. The term "Dual Electrification" is a recognised term. If this article is to remain (dubious), then it really needs to be renamed. --Bhtpbank (talk) 10:41, 31 July 2012 (UTC)[reply]

I agree. Here is a link.[1] Roberttherambler (talk) 23:55, 7 August 2017 (UTC)[reply]

Both systems live

"Premagnetisation of the substation transformers of the AC system can occur". I don't see how, because there is no electrical connection between the third rail and the overhead line, and premagnetisation seems to be a good thing anyway.[2] I always thought the objection to dual electrification was possible interference with signalling track circuits. When the traction supply is DC, the track circuits are AC and vice-versa. If there are both AC and DC traction supplies, then one of them is liable to interfere with the track circuits.

A Neutral Zone between 2 sections will solve this. A recent example would be Jiangtiao line in Chongqing, CN. Johnson.Xia (talk) 17:18, 28 May 2024 (UTC)[reply]
