The Challenge

The started from a comment by @quixoticgeek who said:

Clearly the challenge is to see if you can ride the complete set in one day. Ice 1, 2, 3, t, 3m, 3neo, 4, and L

The rules are thus:

  • take all active ICE models in order, preferably only once
  • finish in Köln to catch the ICE-L on the first day of service
  • one trip between any two stations on each model will suffice
  • I am allowed overnight stops somewhere
  • I can take the same model of ICE multiple times, but only in sequence (so 2, 2, T is valid, but not 2, T, 2)
  • non-ICE trains are valid at any point, in order to maintain the ICE sequence (particularly useful if bahned)
  • all 2s and 4s and Ts are equivalent. Im not chasing down a 402 and an 801, similarly, not having to do a 4 short and a 4 long.
  • if there are 3Ms and TDs in museums, a break to visit them should happen, preferably in sequence or as close to it as possible (genuinely need flexibility here as very few ICEs go to Koblenz) (there aren't)
  • as a bonus, take the other Talgo 230, the EuroCity from Copenhagen to Hamburg

The models I can take are (in order):

  • ICE 1 - 401
  • ICE 2 - 402/801
  • ICE T - 411
  • ICE 3 - 403
  • ICE 3MS (ICE V) - 407
  • ICE 4 - 412
  • ICE 3neo - 408
  • ICE L - 105
