30's or 40's Movie Title Wanted

I am trying to identify a movie from the 30's or 40's involving a loving couple that are split up by their adult children. The last dialog, on a railroad platform as they separate, is " So long, it's been good to know you."

Can anyone identify this movie?

Thanks.

alright mate just thought id say it b4 some over enthusiastic geeky moderator said it but maybe this question would be best asked in the movie forum... cant help you newy mate but again ask the movie forum there clued up at owt like this

^i see the old member took voice 🙄

it can be moved 😬
and i think it would be easier to get the title if you knew who played there 😕

Moving to the Movies forum....

You already asked this question before, and I moved it to the "Movie Trivia" section where it belongs, under the "What's That Movie?" thread.
