It is this engine pictured below. It is a "light" Pacific #6-48061, from the Lionel 2008 Vol.2 catalog. Catalog price was $649.99. These are TMCC with Seuthe smoke units. Go to Carl Tuvesons web site, he has an off the shelf mod to retrofit an MTH fan driven smoke unit, 4 chuffs/revolution and cruise control. These are very nice engines, equal in detail to the Y-3. This and the Mikado were made from all new tooling. There has not been a Legacy pacific made to date.
