Locomotives and heat/cold

[Haby Steven <Haby@acer.edu.au>]

Afternoon all,

With temperatures soaring in S Aust and Vic (and Victoria with power
restrictions/blackouts) a technical, yet timely, question is how well do
various classes/types of locomotives fare in extremely hot and/or humid
conditions.

I'd be interested if anyone had anecdotal evidence of locomotive performance
in extreme weather conditions, e.g. NSU/NTs on the NAR/CR, 39 class
electrics in FNQ, NRs across the Nullabor and so on.

The venerable VR T class I believe suffered from extreme cold and frozen
radiators.

Do electric locomotives suffer as much in the heat as say a diesel,
particularly with the big fans they have to keep the traction motors/engines
cool.

Cheers

In a very hot Melbourne
