The Oslo metro (T-bane, Tunnellbane) have a raised third rail with a cover where the contact is made on the underside. That may be so , but generally its not the 3rd rail that causes everything to grind to a halt. Its usually snow in the motors or signal failures or slipping wheels or frozen points or something else from the Big Bumper Book of Railway Excuses (available at a Christmas discount from Poundshop no doubt). And its really not that hard to fit trains with some brushes and de-icing fluid to keep the 3rd rails clear and if it really becomes a problem I can't see why they couldn't just cover the 3rd rails and use a US style slat contact instead of shoes. I suspect a lot cheaper than converting to overhead. B2003 |
