Certainly not as spiffy and cool as all of the modern era switchers that have been shown here but I am a nostalgia lover and I still admire my circa 1939 Lionel semi-scale 8976 switcher . Still runs smooth and the ringing bell still works fine. She runs slow enough for me.😀When I bought this at my LHS many years ago the pre-war couplers had been swapped out for the post/war couplers. Not original but it fits in with my post-war and modern era rolling stock.
My Railking Imperial USRA 0-6-0 gets all the work in my yard:
BPRC of course!
And the PWC re-release is very nice too.
