The Peninsula Corridor runs from San Francisco to San Jose, where it merges with the Coast Subdivision. It is used by Caltrain and Union Pacific. The total mainline trackage from San Francisco to Palo Alto is about 30 miles. Caltrain Caltrain as we know it today was originated in 1985. However, it's roots can be traced back to 1863, when the San Francisco and San Jose Railroad started the Peninsula Commute service. It was transferred to SP in 1870. Now days, trains run hourly on weekdays (with rush hour services every 20 mins) and evey 90 mins on weekends. These trains use 3 variations of the F40PH (-2, -2CAT, and -2C) hauling 4-5 Nippon-Sharyo cars with a cab car. The Baby Bullet trains skip most stations and run every 30 minutes. They use MP36PH-3C locomotives hauling 6 Bombradier Bi-Level coaches with a cab car. Station List (BB) signifies Baby Bullet stop, (WBB) signifies weekend Baby Bullet. San Francisco (BB) 22nd Street (BB reverse of normal commute) Bayshore South San Francisco San Bruno Millbrae (BB) Broadway (weekends only) Burlingame San Mateo (BB direction of normal commute) Hayward Park Hillsdale Belmont San Carlos Redwood City (BB) Atherton (weekends only) Menlo Park (BB reverse of normal commute) Palo Alto (BB) F40PH-2CAT (and coaches) Your standard F40PH with a Caterpillar generator. Top speed is around 105 MPH. You can find on pretty much any commuter system in the USA. I chose this one simply because they are the ones you'll see most often along the line, and it can easily substitute the others.

I left out anything on freight because I couldn't find anything on it, so if anyone can help it would be great. Thank you for reading!
