Alexandria Derailment and Bridge Destruction

Derailment in Alexandria, VA

One of the reasons that we should not try to dig a trench through Ashland is that a derailment involving tank cars carrying highly hazardous chemicals could have very serious consequences. (An example is the 2014 derailment in Lynchburg, VA). Another serious accident, once more involving tank cars, has taken place — and once more in Virginia. This incident took place in Alexandria, near the Floyd St./Wheel Ave. intersection on May 19th 2018.

The NTSB has not yet issued a report, but the following facts have been reported.

  • 30 cars out of a total of 167 derailed.
  • There were no injuries, either to the train crew or to the public.
  • Firefighters say that the train was not carrying hazardous cargo.
  • The cause of the derailment was a failure with the rail or railbed. (Some of the rail ballast was missing.)
  • The rolling cars “took out” the bridge that collapsed.
  • There has been no major disruption to passenger train service.

Informal discussion suggests that the rebuilding of the bridge could cause a serious delay in the High Speed Rail project.

From the pictures that are available it appears as if CSX was lucky — this event could have had much more serious consequences.

The success of the new transportation systems that are going to replace conventional rail depends on their ability to carry freight at high speed. Therefore, it is encouraging to see that Virgin Hyperloop One is working on such a system.

The problem that almost all rail expansion projects face — Ashland is no exception — is that new tracks destroy property or attractive open areas of land. This means that the best solution is to move into the third dimension, i.e., to construct a tunnel.

Elon Musk receives a lot of publicity to do with his new technologies such as hyperloop, space transportation and electric cars. But it could be that, in the long run, his greatest contribution will be the new technologies that he is developing with his Boring Company.

When various options for the Ashland area were under consideration last year, the idea of constructing a tunnel was summarily dismissed as being too expensive. It could be that Musk will change that way of thinking. As noted in our post The Baltimore/D.C. Project, he claims that current technology is such that the machines for drilling tunnels move at one fourteenth the speed of a snail. He aims to increase tunnel-drilling speeds to equal that of a snail.

The Baltimore/D.C. post described the project that is under way to build a tunnel between those two cities. The “trains” running through it are likely to be some form of hyperloop. Now we learn that the City of Los Angeles has entered into an agreement with the Boring Company that could result in the creation of a network of tunnels underneath that city.

Let’s revisit the idea of a tunnel under Hanover/Ashland. It could be used for high speed trains and other non-stop traffic. The existing rail could be used for non-express trains and selected freight trains.
