These threads always bring out the usual comments detached from reality. While many of the super spotters here might cream themselves at the prospect of living next to a 37 firing up at 4am, those of us with jobs, families and mortgages to pay might be slightly less happy!
In any event it is clear all the people are asking for is some mitigation from the noise and fumes. Surely some acoustic fencing could be erected to reduce the impact of the noise? Surely some different operating principles could be introduced to mitigate the impact of the fumes?
As for the usual comments about moving near to a railway line: They are complaining about the change of train type not trains generally! They might have visited the house at different times of the day and night and noted the units chugging up and down. Not being spotters they perhaps didn't factor in the sudden arrival of a 50 year old, naval gun boat engine powered monster arriving. I mean which reasonable person, in the real world, would?
As for the "they had a choice to move there" sillyness. Many people don't have that choice. They can live where they can afford. Many here seem to miss that point.....
