OK guys, here is the latest, up-to-date information from a spokesperson at ORHF:
1) The move out of Brooklyn Roundhouse date is BY June 30, 2012 NO MATTER WHAT! In other words, even if the new building is not habitable, EVERYTHING must be out of the Brooklyn Roundhouse BY JUNE 30, 2012!!!!!
2) The building is SCHEDULED to be finished WITH AN OCCUPANCY PERMIT, on July 10, 2012.
3)The building is a pre-fabricated METAL structure.
As a suggestion, please don't start asking "What day are you going to move the three steam locomotives?". No body knows, yet.
Also, the steam locomotives will be TOWED the one mile, or so, over to the new ORHF building. They will NOT be fired up!!!!
