  That is probably inspired by EN IEC 81346-2 where “X” indicates a connector of some kind and the numbers following the X identify the connector and the relative position on the connector (for connectors with multiple contacts).

  There is a limit on the spacing of the colour bands though. If you want colours then you have to hit the spots where the correct phosphors are and this limits the usable resolution.

  trains are actually one of the examples where you can get away with lower energy dense fuels, like methanol, ammonia or even compressed hydrogen. sure the range will go down, but for many connections this will not matter that much because it will still be possible to go 1000km with one tank if needed.
