I enjoy your musings... On a more serious note, New Haven was an ALCO road during the steam and diesel eras and did not own any EMD F-series diesels until they bought the FL-9 locomotives beginning in 1955 - same year as they got the EP-5s which were intended for passenger service into Grand Central Terminal, as Rusty said. ALCO S-2 and RS-3 diesels would be more appropriate during the early 1950s - and also electric freight engines such as the EF-3s. MTH has made models of each of these types. The New Haven Safe Milk Company shipped milk - possibly on the main line into New York City but I think that much more milk traffic came down from Vermont on the Rutland and New York Central. Doesn't matter - run whatever tweaks your imagination as long as it says NH...

You should be a railroad historian, Melgar, thanks for the information!
