  • Route: a, b, c, f, e, h, i, l, k, j, c, d, a

    Length: 120 km

    Reason: you've starting industry, 11 industries, finishing industry = starting industry, thus 12 routes to do. A route is minimal 10 km, thus 120 km in total.

  • Helloooooooo!!!

    Here's my response to the shortest route quiz. I can't find any routes less than 110 km so that must mean that there is one. Oh well, here's my submittal:

    A - D - E - B - C - F - I - H - G - J - K - L 110 km KentB US103 Broadway.



    Thank you!!!! :)

  • Hello, I'm Galbenpal, I play on COMM26 Fast Track (4x)


    I have two options for you - Both have same size - 210 kilometers.

    First option is: A,B, C, F, E, D, G, H, I, L, K, J, G, D, A, B, E, H, K, L, I, F,

    Second option is: A, D, G, J, K, H, E, B, C, F, I, L, K, J, G, H, I, F, E, D, A, B

    Even we found 22 letters on each way, you must discounted starting point, in every case is "A" - where distance is 0...

  • B-C-F-I-L-K-J-G-D-A-B-E-D-E-F-E-H-G-H-I-H-K or similar.

    That's 21 tracks or 210 km of travel.

    This is the shortest possible, because there is total of 17 tracks and 6 stations with odd number of tracks. From one of these one starts, in another one ends, which leaves 4 stations you have to use one track twice.

    Edit: I'd like to get the prize on Smoke Chamber.
