Yo Eugene, don't know if your making maps right now but i'd like to throw out an idea for you. Maybe you could take this map, but instead of it driving through a cold and rainy forest at night, maybe it would drive through a searing hot and dry desert in the middle of the day (like 10 am - 12 pm time). Things like cacti (plural for cactus) and desert esque rock formations would pass by as the train goes along. There could be blue skys with a sun. The lighting in the train room would also be brighter.

Again, I don't know if your still making stuff or if you are busy, it's none of my buisness. I was just playing around on this map and that's when I came up with my idea for you. Hope you enjoy :)
