MAINE CENTRAL RAILROAD

Can anyone tell me in which year did the Maine Central discontinue passenger service on the Dover-Foxcroft branch? I read either 1930 or 1933. Also I have in two different books an old black and white photograph, from 1948, with the caption stating that it was a MEC mixed trained going to Dover-Foxcroft. I think this to be an error. Instead I think it was the mixed train to Harmony, ME. Am I right or wrong?
