Track Buggy
The structure of the Track Buggy needs to be strong despite the portability requirements.
Although there exist a variety of portable vehicles and smaller instrumentation trolleys for use on the railway, the larger vehicles tend to be too unwieldy or too heavy to be easily portable, and the smaller trolleys tend to be very application-specific and often do not negotiate unusual track geometries (e.g., switches and crossings) very well.
The Track Buggy is intended as a general-purpose, semi-autonomous railway vehicle that can be transported and operated by a single person. It has four acetal wheels with a P8 profile but a smaller diameter than required by the railway vehicle standard (although check rail clearance is maintained). Early prototypes have been tested on railway track and this design and arrangement of wheels has proved effective.

Because the design is general-purpose, it lends itself to a variety of tasks – a track inspection machine, for example, or a transportation platform – that could contribute to a more effective railway. In addition, it is compact and lightweight, and safe and easy to use.
The aim of the project is to design, make and test a semi-autonomous general purpose railway vehicle that one person can transport, assemble and use.
