Potentially false claim[edit]

Potentially false claim that They are the only class of electric locomotives in revenue service in New Zealand. does New Zealand AM class electrical multiple unit count as an electric revenue service locomotive? Forces2019 (talk) 05:28, 29 March 2020 (UTC)[reply]

The New Zealand AM class electric multiple units are Electric multiple unit, not locomotives.Easyg777 (talk) 11:20, 29 March 2020 (UTC)[reply]

It's not a false claim at all. The EFs are locomotives, the AMs are Electric Multiple Units --LJ Holden 21:04, 29 March 2020 (UTC)[reply]

Auckland Electrification[edit]

I don't understand the statement that the EF class locomotives cannot operate in the Auckland area because the electrification in that area operates at a higher current and the rectifiers in the EF class would need to be replaced. What does "higher current" mean in this context? 1.129.107.180 (talk) 09:35, 16 February 2021 (UTC)[reply]

The overhead power supply in Auckland is capable of supplying a much higher current than the EF class can handle, and so there would likely be a big bang if it was attempted. pcuser42 (talk) 09:40, 16 February 2021 (UTC)[reply]
But doesn't the current being drawn depend on what the locomotive is demanding, according to its load and the gradient? Or is it to do with the fault level - the Auckland network can supply a greater current in a fault situation such as a short-circuit within the loco? 1.129.107.180 (talk) 09:55, 16 February 2021 (UTC)[reply]
I believe it's the fault level. pcuser42 (talk) 21:50, 16 February 2021 (UTC)[reply]
