This will be a challenging trophy/achievement in TSW 2. 10,000 miles is almost half way round the world
It will be tough because all the routes are short and trying to do it on a commuter/metro route will take forever as your miles to time ratio will very poor due to the stop/start nature of it and low speeds. Take a metro route such as the Bakerloo line: 14.4 miles and it is timetabled 48 minutes. 10000/14.4 = 694 journeys (347 return journeys) or 555 hours in the seat. Now I don’t know how many journeys a Bakerloo Train operator doesn’t in a day but I will guess 3 return trips on a typical day so 347 return trips / 3 (or 555 hours / (0.8 hours * 6) ) = 115 productive days based upon 3 return trips a day. Compare this to an intercity/long distance route (if and when one comes out), you will achieve it a lot quicker. Any mainline job on a given day that I do is no less than 250miles return trip and can be up to 400/450 miles which corresponds to between 3-6 hours of driving time in a shift. So 10000 miles would take me in real about productive 30 days (or 30 return trips) or 135 hours in the seat. It’s still a lot and certainly I would never spend this time on a simulator even if intercity routes were available. It would even be quicker on a high speed route such as the bullet train or the TGV, etc... (Come to think of it, I would hate to see how many miles I’ve driven in GTA or how many miles I’ve ridden in Red dead redemption) Here is a comparison of miles per minute on 3 different type of routes- metro, commuter and intercity: Bakerloo line: 0.3 miles a minute GWE turbo: 0.6 miles a minute GWE HST: 1.44 miles a minute
Driving trains over a very long distance is not a question of skill, but of fatigue resistance. So it will be easy to do this for users who are used to 24/7 gaming .... For me this is not worth a trophy under any circumstances.
Now, the question is, does that mean any single rail vehicle (not hard but very time consuming) or a total of all rail vehicles (less time consuming)?
The list is on TrueAchievements. It's likely the PS4 game will have the same. Already seen some unlocked in the streams on Steam and they were the same. https://www.trueachievements.com/game/Train-Sim-World-2/achievements
