EP-5, 2379 R.G. F-3, 746 N&W J, 2373 CP F-3, 602 Seaboard NW2, not too bad). Other new items included the "Girls Set"(1587S), Canadian Pacific F-3 pass.set(2296W), 746 N&W "J" steamer frt.sets(2295WS or 2297WS), Rio Grande F-3 set(2291W), Super O track was new in 57, 2243 S.F F-3 AB, 3444 Erie cop & hobo car, 6800 flat with airplane, 6801 flat with boat, 611 Jersey Central NW2, 2339 Wabash GP-7, 42 Picatinny Arsenal switcher, 55 Tie-jector, 264 fork-lift, 195 floodlight, 128 animated newstand, 334 dispatch board, 345 culvert unloader(to go with the 342 from 56), and more. 1957 was a premier year for the set collector, even the cheap sets were cool. This catalog year is also great for Lionel reference, alot of history went down in 57.
