I never expected to see a B&M fluted side sleeper at Los Angeles UPT in 2010. I have no idea which train it may have been assigned to. There were a few named run throughs from New York and Washington to New Hampshire and Maine after WW-II, but have no info of their consists.
It seems to be a privately-owned car used on excursions. Interesting history on it at http://www.salisburybeachrailcar.com/
Thanks for the link. I had no idea of her history or her lovely interior. I never rode in her, though could have if she had been in service before 1942. I rode a combined New Haven/B&M overnight from New York to New Hampshire summers during WWII. My mother and I stayed with relatives while my father was "sequestered" in a secret lab helping develop radar. We saw him only on Christmas days, then for only two hours under guard. I was the "man" of the house, though only 7-10 years old. I'll never forget the phrase "there's a war on, doncha know!", which was the answer to almost every question or comment I made. I hope America never has to experience that again.
