Passenger Trains > Rails painted white on Metro North east of RyeDate: 09/23/21 13:49 Rails painted white on Metro North east of Rye Author: rbenko On a MN train to New Haven - just east of the Rye, NY station I noticed on the two southbound/westbound tracks each of the rails were painted white all the way up to the top of the rail. It was like this for about a quarter of a mile. Pretty interesting looking. Anyone know what the purpose of this is?

Trouble is the paint hides some types of rail defects. That is the reason engine and car couplers are never painted.

Or where the track structure is particularly susceptible to kinks?

I heard something on the radio the other day and also saw it on the Internet: reportedly, scientists at Purdue University have come up with a white paint that is so white that it reflects about 98% of light. That translates to a significant savings in energy use if painted on a building, etc. Victor Edited 1 time(s). Last edit at 09/26/21 18:44 by wabash2800. |
