The diamonds on the left of the double slip switches are unique. Each diamond, instead of four frogs, has two frogs and two "moving switch points" to reduce wheel and rail impacts.Double slip switch, space savers, but they create there own special issues.
Getting ice and snow up here in NY. Winter had taken a break, but is back again.
If they had done that in Savanah a couple of years ago, I would have had my cross country trip to LA to catch the cruise from LA to Ft Lauderdale. Unfortunately (as was previously reported) the switch froze and the unfroze while the Meteor was backing into the station and derailed it, resulting in the cancellation of my trip the next day.A lot of places in the country don’t need switch heaters. Look at SC for instance we get a big snow (2-3 inches) maybe every four or five years. We don’t need a switch heater at all. So we just use kerosene soaked rags and set the switch points on fire to melt the snow.
In the Netherlands we have natural gas heated installations which use a liquid to transfer the heat to the switches.I wonder how the Shinkansen and ICE handle it (no pun intended).
