Yup... Called the Sunset Route from the old SP. Lordsburg Sub from El Paso to Tucson.
There are a number of sidings which are being connected and as they are connected, it now becomes a second main track.
On an average day, right now - without any "events" which would impact operations, we are averaging 50-55 trains a day in that corridor. As more single track is turned into double track the volumes will increase..
Most of the old bridges out there were creosote piling type design.. Those are being replaced with pre-stressed concrete and some steel.
Trying to keep up with the demand.... I'll have to dig around and see if there is number associated with the cost of this corridor alone. We are doing the same thing on a couple more primary routes. We even have triple track in some locations...
I'm glad to see them fixing track and glad the RR business is growing.
Great thing about FR is someone always knows what is really going on. All I hear about the RR work is about 15th hand by the time I hear it.
