I am happy with the release of Peninsula Corridor, but I find there are two iconic engines and a cab car on this route missing. 1: Union Pacific gp60 With only four axels, this engine isn't your common "geep." Holding 3800 horsepower, this is EMD's most powerful of the "gp" class. Holding a 3700 gallon diesel tank, and advanced technology for it's time, this would make a great addition along side Peninsula Corridor running dirt and freight trains. Caltrain MP36PH-3C "Baby Bullet" With max speed of 82-102, this was a ideal passenger locomotive. With two separate engines instead of one, noise and emissions are lower than other mp36 class. Along side the MP36PH-3C, is the Bombardier cab car/ coaches. As stated, Peninsula Corridor is a very new route so any add on's for it will most likely come in the far future if at all. Though in my opinion, later on in 2020 this would be a ideal engine pack.
