Tupolev Tu-134
Although Tupolev had already built jet airliners Tu‑104 and Tu‑124, seeing the Caravelle and DC‑9 with rear mounted engines prompted the Russian design bureau to adopt this feature as well. The result was the Tu-134, NATO code name Crusty. Clearly the aircraft was derived from the Tu‑104/Tu‑124, but then with a T‑tail to keep the horizontal stabiliser clear from the jet exhaust of the engines attached to the rear fuselage. The aircraft retains the typical low mounted Tupolev wings with anhedral and main landing gear retracting rearward in pods extending from the trailing edge of the wings. Each main landing gear has a four wheel bogey.

Different versions
How to recognise the different versions of the Tupolev Tu-134 will be added later.
Confusion possible with
Fokker F28 & Fokker 70/100
The Fokker jets are similar in size, but have two wheel main landing gears retracting in the fuselage, an air brake in the tail cone and oval cabin windows, to name a few differences.
BAC One-Eleven
The same applies to the BAC One-Eleven, although it lacks the air brakes and also has no dorsal fin. Last but not least it has a wider fuselage than the Tu‑134.
Douglas DC-9
Also the DC-9 has two wheel main landings gears retracting sideward in the fuselage, and additionally it has cockpit eyebrow windows and rectangular cabin windows.
Canadair Regional Jet 900/1000
Especially the longer versions of the Canadair Regional Jet could be mistaken for the Tu-134. However, there are many differences: main landing gear, cockpit windows, cabin windows, engine nacelles and (lack) of winglets.
