Excerpt: "I'm crazy about trains! says Doc Holliday (Jason Robards) to his friend Wyatt Earp (James Garner) in Hour of the Gun (Sturges Ch. 6), explaining why he's waiting on the Contention train. Of course he's really there to help Earp get his revenge on Ike Clanton (Robert Ryan) - but then we never quite know with Doc Holliday.

Subject of this thesis is design of a timber trailer with manual control. The designed timber trailer is one of the small machines that are used for a low–volume timber production. This timber trailer operates in a rough terrain – its outstanding feature is the ability to operate on steep slopes and overcome obstacles. The concept of the control system and the safe seating of a driver are contributions to the field of ergonomics. This machine is considerate of a forest environment because it minimizes formation of soil erosion. Easy washability and maintenance are other criteria of this proposal. The functional point of the design is firmed by the purposeful and aesthetic shaping which is unique in this category. Comparison of the proposal presented in this thesis with available machines demonstrates that work of designer is indispensable part of a machine development process.
