The engines were probably removed so they could be used as spare parts. I couldn't even tell for certain if it had a T tail or not but I think it did. There are a lot of different airliner designs that used rear engines (2, 3, or even 4) with a T tail. Here are just a few:
Boeing 727
DC-9 and MD-8X derivatives
British Trident
Fokker F-28 (F-70 & F-100 are bigger)
Il-62 (note the 4 engines)
Current Events » in reply to Most skilled observers have said it is not a 707, but some plane with engines in the tail (which seems to be missing) (n/t)
Yeah, the wings are too far back for it to be a 707
