If you're looking for a versatile diesel locomotive fitting any time period from 1954 on, the GP-9 "torpedo boat" (or "torpedo tube") is a must! Features of this Phase II unit include: steam generator detail on top of the short hood, larger fuel tank, side sills with water-fill detail, dual flywheel equipped 5-pole skewed armature motor with a low friction mechanism and twin brass flywheel, and roof-mounted airtanks which give the locomotive its nickname. Impressive details include numbers printed on the illuminated number boards, full end pilot plates featuring multiple unit hoses, and highly accurate painting and printing jobs.
