In order:
- CNJ
- PRR
- Amtrak
- New Jersey Transit / NJ DOT
- ATSF
- SP
- Conrail
- Penn Central
ATSF and SP are a little odd on this list I realize, but I adopted those roads when I started operating trains at my 3R club, the Paradise & Pacific, in Scottsdale AZ.
The first two I predominantly now model in 2 rail O. However, single largest group of locomotives and rolling stock in my collection is in Amtrak in 3 rail followed by PRR in 2 rail.
The logic? Most of my most formative train memories were from early Conrail and 1980's era Amtrak. Why I model CNJ / PRR from circa 1953-1957 on the Jersey shore is a story I've told one too many times on this forum so I won't repeat it. However, these photos are worth repeating as they represent what really gets me excited in O scale trains:
