OW TO SOLVE DRAINAGE PROBLEMS
What can a track maintenance manager do today when he finds himself with drain-
age problems? He knows that poor drainage creates a lubricating effect in ballast. Ties ly-
ing in wet, muddy ballast deteriorate more rapidly. If not corrected, there will be trouble
with track heaving in cold weather.
Loram Maintenance of Way Inc. сan provide an answer for the track maintenance
manager. An attack on poor drainage concentrates on moving water away from the road-
bed into a properly maintained ditch.
Shoulder ballast cleaning is not a new process, but is one that is receiving increased
attention because it economically speeds the movement of water from the track section.
A self-propelled Loram shoulder ballast cleaner picks up the entire shoulder of even
the deepest ballast section, removes mud, returns clean ballast to track and regulates
cleaned ballast to specified slopes. The track maintenance manager does not need auxiliary
equipment and needs to provide only supervisory manpower. Because shoulder ballast
cleaning does not affect alignment or disturb elevation, the track can go into service im-
mediately after cleaning.
The second part of the attack on poor drainage involves a relatively new piece of
equipment – the Badger ditch cleaning machine. The self-propelled Badger has a travel
speed of 45 mph, working speed of up to 2 mph and material handling capacity of 1,000
tones per hour.
The machine can clean the ditch on either side of track without the necessity of turn-
ing the machine. Ditch width can be varied from 30in to 54in and the ditch can be located
anywhere between 6ft and 18ft from the track center and up to 4ft below the top of the rail.
The Badger is exceptionally well adapted to working in extremely wet conditions,
removing material which has a high percentage of water. It is a drainage tool designed
specially to function efficiently in the railroad environment. As a result, the Loram Badger
is much more economical than conventional ditching equipment when utilized for track
drainage work. Besides being economical, the Badger also does high quality work.
