From The Telegraph:
House price growth at stations on Southern Rail's routes has ground to a halt as strikes by the RMT Union continue to make commuters' lives a misery.
New research by the online estate agency HouseSimple found that properties on the Brighton Mainline, Mainline West and East routes have fallen in value by an average of 0.4pc, losing £1,875 in value in the last three months.
This is not due to a general slump in house prices in the area during a traditional summer lull: in the south-east of England, house prices have risen on average 2.4pc between June and August, according to the Land Registry.
Von T's rings assume constant travelling speed (in the days of horses and carts) so it is only distance that matters; what actually matters is time, cost and hassle, so if a train service is less reliable, that is effectively further away from The Centre.
