Southern Railway — Idling in residential area

I live beside your railroad at: 12235 101A Ave Surrey, B.C. V3V7J[protected]
o The idling occurs quite often in the late evening and wakes the entire household. There is work in the morning making it difficult to get back to sleep.
o This also occurs during the daytime and the fumes become so strong that I and the pets need to go indoors.

The duration of this idling goes anywhere from 20 mins - 60 mins.

I realise its an industry but wonder why it is performed in the residential area when the rail yards and industry parks are not far away ?
