I hope the’ re some creative modellers here that also may take Dutch N.S. trains in consideration, they were also very popular on oTTD and Locomotion.
The Dutch N.S. trains all have wonderful colors, are very modern and just look bad-ass. N.S. also has a nice history with earlier trains, they just don’t go as far back to 1850 as far as I know. So most trains are modern which is nice in my opinion.
