I am curious how you picked the line you chose. Was it the color, the scenery it ran through, being familier with it, seeing it everyday or what. I know that may have to be my first decision here and I am curious how others made theirs.
I chose Conrail as they ran right behind my house for the first 14 years of my life, I just love the bright blue locomotives. Since Conrail no longer exists, it leaves me a lot of freedom when it comes to modeling them in current times. I get to pull a lot of things I find interesting on other current day Class 1's and adapt them to fit my needs.
