I am very impressed by the Industrial building and especially the overhead crane !! Having worked many many years in Freight Forwarding / Shipping / Export Packing I have spent a lot of time inside similar warehouses/freight depots and can vouch for the realism with only 2 exceptions -(1) it's too clean and (2) It's empty
Seriously though you done a fantastic job. The only thing I could suggest and that's all it is and definitely not a criticism is to attach to the crane a yellow or black electrical wire with a small block at the bottom to act as the crane control.
I have planning to have an export packing warehouse on my layout and have been looking at a complete scratchbuild until now until I saw this, maybe with 2 overhead cranes.
although I may have to age the building around the 1960's
PS Like the DB Schenkers naming as they are a large global freight forwarder and do run railfreight services.
Face by God & Rugby. God put the good bits in and playing Rugby moved them around and made them 'interesting.'
