1,1 tonne mortar shell? Then again I suppose vehicle is somewhat expensive and have limited payload so not that big of a bomb...

... and nobody actually saved or gained any time.

Yawn. Still no real test-track for full size trainsets like the Transrapid had in https://en.wikipedia.org/wiki/Emsland_test_facility https://en.wikipedia.org/wiki/Emsland_test_facility While https://en.wikipedia.org/wiki/Shanghai_maglev_train https://en.wikipedia.org/wiki/Shanghai_maglev_train doesn't do so well for various reasons. Meanwhile the https://en.wikipedia.org/wiki/Ch%C5%AB%C5%8D_Shinkansen https://en.wikipedia.org/wiki/Ch%C5%AB%C5%8D_Shinkansen is holding the world record for the fastest train with passengers, at slightly over 500kph in somewhat regular operation over slightly more than 40km of testing track. And over 600kph in a test run, also with people on board! https://en.wikipedia.org/wiki/SCMaglev https://en.wikipedia.org/wiki/SCMaglev I sense a certain loop of hype, here... Now it remains to be seen how the final costs of building unit of track compare to other modes of transportation, and its socio-economical impacts. Like cutting through the landscape, tunneling, how it's usable for freight, if ever? I'll be hyping something else here, which is also in operation already: Flight! Just upgraded with https://en.wikipedia.org/wiki/Liquid_hydrogen https://en.wikipedia.org/wiki/Liquid_hydrogen or https://en.wikipedia.org/wiki/Slush_hydrogen https://en.wikipedia.org/wiki/Slush_hydrogen driving superconducting electropropulsion for STOL/VTOL. No superconducting materials at room temperature? Just use the liquified hydrogen, let it flow around the electrics, both in liquid form, and the necessary off-gassing. Easy, innit? I'll show myself out now...
