I know the Capital Limited's Crew Changes, they are at Toledo, Ohio, and Pittsburgh, PA. I'd assume the Lake Shore conducts Crew Changes at Toledo, Ohio, Buffalo, NY and Albany, NY? Correct me if I am wrong about the LSL as the last time i took it i was only 6 months old. As for the Michigan Services... The Pere Marquette should be able to make it on one crew but if they have to switch it usually comes at Hammond/Whiting, IN. The Blue Water and Wolverines switch engineers at Battle Creek, MI, but the conductors continue to the terminus, the engineer will sit in Battle Creek and wait for the next trip back to where they terminated (Chicago, Pontiac, and Port Huron).
