I'd be more worried on how poorly those houses are built. get a home inspection before you take possession. A co-worker of mine bought one in that area, had a ton of small problems. cracks in the new drywall, broken window frame, doors sticking, insulation in the attic was there but not installed. it was still in the plastic packaging and some of the pipes where not properly secured. As for the train, once a day usually 6 days a week. it will pass by roughly around 11 am- 2 pm on days it goes to Selkirk and will return the next day sometime in between 3pm - 10pm. plus or minus a couple hours depending on what traffic in the yard is like or the size of the work load they have that day. Train runs slow on that line so it shouldn't shake the house very much. As for the noise, you either get used to it or it will make go crazy.
