This is a four stall engine shed based on American design. It is a mocrossing object with rails and concrete slab floor and is designed to match the five track Transfer Table 1, allowing one track to bypass the shed.
Join the tracks in the building to the transfer table with sections of invisible track and squash it up to the table tracks. Make sure the blue hole cut for the inspection pit is covered by adjusting the position of the engine shed.
