The Corbin field railway was a transportable, narrow-gauge field railway (Corbin system) with wooden, metal-clad track yokes and partly single-axle wagons, which was developed around 1873.
history
A model made by Max Strakosch in Brno was exhibited at the Vienna World Exhibition in 1873 . At this point in time the system had already been used many times.
The connection of the individual track yoke frames was made by short straps of 130 mm length, which are attached to one end of the long sleepers by a screw bolt with nut and held together at the other end by inserting a locking pin, which means that the track can be laid extremely quickly and again dismantled.
A double-track field railway of this type was laid on the Seelowitz leasehold in Moravia , which led to a cable giant on a ridge . The light railway was 379.3 m long. It was used to transport lime and marl from the upper part of the mountain, which was rich in these materials, to the wire rope giant. The loaded, downward rolling carriage pulled the empty train uphill with a rope wound around a horizontal pulley.
Each train consisted of 18 small cars coupled together that carried baskets that were easy to lift off and move. These 18 baskets held a total of 30 inch cents (1.5 t). Since a train went downhill every 13 minutes, the field train could transport 1200 quintals (60 t) to the wire rope giant in 11 hours per working day.
Tracks
The track had a gauge of 420 mm and consisted of wooden yokes , which were then called frames. These were made of 80 mm high and 40 mm thick slats, which were connected by crossbars and continuous screw bolts, and were nailed with rails made of 35 × 2 mm thick band iron.
In the track yokes for arches, the curvature was achieved by sawing cuts in the wooden long sleepers, the curvature was held in place with special tapes, and the track gauge was fixed by using the aforementioned pressure and tension bolts.
dare
The cars were specially designed for better cornering. With the exception of the first car, they only had two wheels. Only the foremost car was four-wheeled, while all following had only two wheels and were connected to the neighboring car by a long drawbar. The connection was ensured by a bolt riveted into the end of the trailer coupling rod, which allowed the trains to run through even small radii.
