Jailbar is just the fact it has a criss-cross grill as opposed to a fabric covering? The water tower certainly is a Jailbar if that is the case.
Oh trust me it works - we let it sing. It has a brand new blue control box (The original FS one is gone) and according to the crew in the station it goes off every month. It may now, however be switched off in the near future but I will likely take possession of it at the start of next year and ensure it goes to a good home - It needs a crane though!
I have to say, Cincinnati's Thunderbolts are in exceptional condition!
