Engine sounds
45/1 engine note
I have recently been listening to some of my old train recordings.
And it seems that 45/1's make a different sound to 45/0's, 46's and 47's. Is this true ?
45/1's are characterised by slowly building up the power then a whoosing type sound then a high pitched wine.
Whereas 45/0's 46's 47's have a throaty rythmic build up of revs similar to the smaller engined sulzers.
Which in my opinion is a much richer pleasant sound to the 45/1's.
Do the 45/1's make a different sound or have i imagined this?
I know the 45/1's had their auxillary generation gear removed and replaced with a brush alternator. Would that make a difference to the engine note ?
Any one got any answers ? I always found 45/1 recordings non descript and dissapointing once the tickover turned into acceleration.
