Bering Strait Tunnel

[NordikNerd]

85 km would be the length of that tunnel.

The longest underwater tunnel to this day is the 53km long Seikan-tunnel, which is situated in Japan.

transport

passengers: 1,700,000 persons/year
freight: >5,000,000 tons/year

Now are these figures a goal for the Bering Strait tunnel ? There must be a similar profit to finance the project.

Here's why:

Adding another rail to the inside of Indian Gauge (1676mm) to add Standard gauge capability is a WHOLE lot easier than adding to the outside of Standard Gauge rail. When you increase the width of tracks you have to think about tunnel size, distance between parallel tracks, wider ballasts, etc.

There is no indian gauge now near Eastern Russia. There is 1435 mm gauge, though.

Does China plan any double gauge tracks into Eastern Russia? A logical start could be the Manchurian Line. Suifenhe is closer to the seaport of Haishenwei than to Dalian or Dandong... and even Harbin may find Haishenwei a short cut, especially if using Dalian or Dandong means that the ship then has to sail all around Korea.

Indian gauge is also, plain and simply, more expensive to construct. Sorry to disappoint you.

*BIG PROBLEM* here (and I've mentioned it many times before) - Russian broad gauge (1520 mm) and 'standard' gauge (1435 mm) have about the most insidious difference between them of all - 85 mm. They are too close to allow the easy creation of dual-gauge track by laying a third running rail and too far apart to be able to run directly between them.

Dual gauge track would require four running rails.

Indian broad gauge, large loading gauge, long curve radii, concrete sleepers and 25kV AC electrification are required.

Adding another rail to the wooden sleepers capability is a whole much a lot easier than adding another rail to the concrete sleepers. Most rail lines in USA and Canada have wooden sleepers. Rail networks in USA and Canada should be converted from 1435mm (standard gauge) to 1676mm (Indian gauge) and electrified 25kV AC overhead lines and nationalized. And family styles in USA and Canada should be changed from nuclear families to joint families.

Possible 3-rail dual gauge:
1676mm and 1435mm (241mm difference)

Impossible 3-rail dual gauge:
1520mm and 1435mm (85mm difference)
1520mm and 1676mm (156mm difference)

4-rail dual gauge:
1520mm and 1435mm (bonus 1829mm)
1520mm and 1676mm (bonus 2000mm)

Iran should release eastern part and China should release northern- and western parts.
(then gauge conversion from 1435mm to 1524mm in these areas)

Here's some four rail dual gauge track for you in Belarus.

Russian gauge (1520mm) and North American network using standard gauge (1435mm) are only 85mm difference. Argentina, India and Pakistan are using Indian gauge (1676mm), also should be considered. Standard gauge and Indian gauge are 241mm difference, while Russian gauge and Indian gauge are only 156mm difference.

Also, Indian gauge and Brunel's broad gauge (2140mm) are 464mm difference, and Brunel's broad gauge and Nazi broad gauge (3000mm) are 860mm difference.

Russian gauge and either standard gauge or Indian gauge cannot get 3-rail dual-gauged, need to be 4-rails. Indian gauge and standard gauge can be 3-rail dual-gauged. Brunel's broad gauge and either standard gauge, Russian gauge or Indian gauge can be 3-rail dual-gauged. Nazi broad gauge and Brunel's broad gauge can be 3-rail dual-gauged.

Loading gauge upper limits:
4100mm wide and 6150mm tall for standard gauge (1435mm) tracks.
4185mm wide and 6150mm tall for Russian gauge (1520mm) tracks.
4341mm wide and 7000mm tall for Indian gauge (1676mm) tracks.
5140mm wide and 7000mm tall for Brunel's broad gauge (2140mm) tracks.
6000mm wide and 7000mm tall for Nazi broad gauge (3000mm) tracks.
(calculate from Eurotunnel Shuttle, double-stack container trains and early 1940s Nazi-German plans)
