BIG ENGINES:
In many of my maps I have seldom found any use of Big engines such as the Challenger or the Big Boy Class. In this scenario huge articulated engines will be useful due to long hauls and mountanious terrain (I wish Beyer-Garrath engines were avaiable in RRT, they will be represented by huge North American Mallets).
Besides the map attached to this topic you will find some screenshots, showing how I have built the trunk line with maximum grades of 3%.
As usual, any comments, advice and suggestions are wellcome
