I do not get this part. These are not advantages of tube v railway track, because a railway track can also be built above ground and can also be build from prefabbed sections. In fact I would think that building a railway track would be much cheaper than building an airtight tube.
- DannyBee 13y agoRailway track built above ground has to support weight of the cars, which seems significantly higher ....
- benjamincburns 13y agoUnless Musk has found a way to make the cars weightless, the tube must support the weight of the cars. Further, the pylons must support the weight of the tube and the cars, over a smaller footprint.
- DannyBee 13y agoRailway cars weigh approximate 30 tons (unloaded) to 140 tons (loaded). Even a Ford F150 truck only weighs 2 tons.
