The Lionel 1665 Lionel Lines 0-4-0 Steam Locomotive from 1946. The 1665 steam engine was classified by Lionel as a Switcher steam locomotive. In addition to being sold separately, it was also included in one work train set for 1946 — set 1407B. The 1665 steam switcher shares its boiler casting and tender with the prewar 1662 — but with updated postwar knuckle couplers and trucks. This switcher also shared its boiler casting with future postwar switchers such as the 1615, 1625 and 1656. The 1665 bell-ringing steam switcher was only available for a single year — 1946. With its short production cycle of only a single year — as well as being the most sought-after of all postwar steam switchers — the 1665 has become the hardest and most desireable of the four steam switchers produced by Lionel in the postwar era. The 1665 is a high quality and durability locomotive.
