We collected and will operate mostly modern era. Which is why we have an 8 1/2" elevation change... double stack containers will be able to run through tunnels without the need to "daylight" them. (Hindsight is 20/20, right? Appalachian railroads, talking to you.) I did, however, have to modify some portals. Interestingly enough, MTH Premier husky stacks won't fit it MTH tunnel portals. I was able to modify them to work by sacrificing one, cutting off the bottom two rows of bricks and adding them to another to raise its overall height (left one in picture). One sacrificial portal can make 6 working portals, before the bricks start to arch over and will no longer fit. Note, there is some variation to finish of portals from different batches. My sacrificial portal was a partner to and therefor a perfect color match to the first heightened one, but others can have a slightly different shade of grey (right one in picture) and may need to be painted to match.
