Hi, I'm looking to buy a refurbished flat which literally backs onto the Haywards Heath mainline. It is right next to the station, so the trains won't be going past at speed but slowly chugging in. The flat I am looking at, I would guess is around 20-30 metres away from the line, with a few of flats in front of it (same block). I've seen the showroom flats and they seem to be well insulated and with double glazing windows, I heard a few coming in whilst there and they didn't seem too loud, but hearing them during the day and at the dead of the night isn't the same. I also heard a couple of Express trains rushing through the station which were quite loud, but this is fine if they don't go through after midnight. My other concern is as they are refurbished, they may not be as sound proof as purpose built flats, but I am by no means an expert in this area! So I was hoping anyone with knowledge of the Haywards Heath line would be able to advise on the following: - How loud trains stopping at the station really are - Whether there are any freight/milk trains on the Haywards Heath line after midnight - How many Express trains go through the station during the night if any (again, after midnight) - Does anyone actually live close to the line, if so, what are your experiences? Thanks in advance!
