Tarka Line

I went hiking in England in the past week. Although most of my intercity travel was made by coach bus (for budgetary and logistical reasons), being who I am, I still had to slip a train ride in there somewhere, didn't I.

What could be a more suitable way to end my hike than a train ride on the quaint and picturesque single track Tarka Line from Barnstaple to Exeter? In the gentle green hills of Devon, DMUs on this line traverse a scenic 40 miles along the Rivers Creedy, Yeo, and Taw.

The Tarka Line got its name from Tarka the Otter, a local animal hero from a novel by the same name. It is part of what used to be the North Devon Railway between Bideford and Exeter. Today, the line terminates in Barnstaple.

Instead, here is another system, currently under construction, that will serve as a case study to the rest of the world on the mass adoption of maglev technology.

Formally called the Chūō Shinkansen, the new central mainline in Japan is fundamentally different than the high-speed lines that come before it. It utilizes the SCMaglev, or Super Condicting Magnetic-levitation, technology that has been under development since 1962. The SCMaglev uses one of the three principal implementations of magnetic levitation, called EDS, or Electro Dynamic Suspension. The other two consist of EMS (Electro Magmetic Suspension), used by Transrapid, and Inductrack System (Permanent Magnet Passive Suspension, which is a passi…
