Just can't help it, and pardon the levity, but - - the New Haven EP3! - and you know why...
PS: OK, OK, so I grew up in New Rochelle, NY, a few blocks from Shell interlocking (and a few miles from the fabulous, long gone O-scale Eastern Lines of the Westchester Model Club). The really sad part is that I went to high school in the Bronx, from 1954-1958, a few blocks from the still-active Van Nest electric shops of the New Haven - - and didn't even know at the time that they were there!
