Train Sim World 2020

In this guide I will cover 2 easy methods to obtain this achievement.

Method 1 requires you to have the West Somerset Railway DLC, don't worry if you don't the other method does not require the WSR. First go to the WSR > Timetable > Select the Class 20 > Start the service called Locomotive Exchange at Minehead which starts at 11:55, this requires you to take the locomotive from the yard at Minehead and couple to the coaches in the platform. After you have reached the signal at the other side of the Level Crossing, reverse the loco back into the platform, before you couple the loco to the coaches, save the game, this saves you doing the previous steps over and over. After you have saved the game, couple the coaches and the service should complete. Upon returning to the main menu, navigate back to the WSR and press "Last Played". After you load back in simply couple the coaches and the service should complete. Rinse and repeat until the achievement pops.

Method 2 does not require the WSR, this can be done on Tees Valley Line in a similar fashion, although it takes longer to set up. Navigate to TVL > Timetable > Select the Class 20 > Start the service called 0Z05 Redcar Ore Terminal, this requires you to unload coke wagons at Redcar and run round the wagons ready for the return journey. Before you start moving I would suggest checking that the junction after the unloading point is set correctly or else you will go down the wrong track and you would have to reverse all the way back or restart the service completely. Make it is set to how it looks in the picture. When you get to the unloader make sure to keep your speed at 1.5 - 2.5 MPH in order for the wagons to unload properly. After wagons have unloaded move up to the indicated marker, uncouple from the wagons and move up to the headshunt. Run round the wagons. Before you couple to the wagons, similar to method 1, save your game and the couple to the wagons. Again upon returning to the main menu, navigate back to TVL and press "Last Played". After you load back in simply couple to the hoppers and the service should complete. Rinse and repeat until the achievement pops.

Hopefully these 2 methods can help you unlock this achievement.
