Abstract: A mobile machine for clearing ballast from a ballast bed section wherefrom a tie has been removed comprises a machine frame extending in a longitudinal direction, undercarriages supporting the machine frame for mobility on a track supported on the ballast bed, and a ballast clearing device vertically adjustably mounted on the machine frame for clearing ballast from the ballast bed section. The ballast clearing device comprises an inner ballast clearing element arranged on the gage side of at least one rail and pivotal by a pivoting drive in a plane extending transversely to the longitudinal direction about an axis extending in the longitudinal direction, and an outer ballast clearing element vertically adjustable by a vertical adjustment drive independent of the inner ballast clearing element and arranged on the field side of the rail.

Abstract: A ballast plow that is attached to a KERSHAW ballast regulator wing. The plow will be attached to the wing so that it can be moved toward and away from the wing, and in addition, it can be moved up and down and can be rotated from side to side. The plow will allow the device to extend its reach to an area outside the normal ballast area of a railroad track and to clear away brush and small trees which might impinge upon the ballast area. The plow reclaims ballast, drainage, and creates an improved walkway, thus providing a safe working area.

Abstract: Apparatus for laying underground cable or conduit (such as innerduct) includes a vertical cable plow connected to the boom of an excavator, the excavator being mounted on a first flat-bed rail car, and a second flat-bed rail car following the first for carrying supply reels of cable or conduit fed from the second car to the first. Cable guides guide the cable or conduit from the supply reels to the plowshare and through the plow assembly to the desired subterranean level in a ditch made by the plow. The first and second flat-bed cars are preferably pulled by a pair of conventional diesel-electric locomotives. A rigid element mountable to the first flat-bed rail car and extending outward from either side of the first flat-bed rail car transfers torque on the plowing assembly to the rail car. The rigid element (“boot”) is preferably removable to temporarily narrow the apparatus for travel mode. The apparatus may be installed on a flat-bed truck or a canal barge instead of a rail car.

Abstract: A ballast plow (1) comprises a machine frame (6) supported on on-track undercarriages (2), with which is associated a center plow (5) which is vertically adjustable by means of drives and on each longitudinal side of the machine a vertically adjustable shoulder plow (8) having a plow blade (20) which may be brought into contact with ballast. The shoulder plow is provided with an articulation point (13) and a telescopically extendable carrier frame (12) extending perpendicularly to the longitudinal direction of the machine. The articulation point (13) is situated in each case--viewed in the transverse direction of the machine--on the longitudinal side of the machine which is further away from the associated plow blade (20) of the shoulder plow (8). The plow blade (20) is mounted for pivoting about an axis (21) extending in the longitudinal direction of the machine and is connected to a shoulder angle adjustment drive (15).

Abstract: A bucket loader wherein the bucket is pivotally mounted at one end of an arm. The other end of the arm is pivotably connected to the locomotive of a multiple-trolley train which is mounted for travel along an overhead monorail in a surface mine or in an underground excavation. The bucket can be tilted by two chains each of which is connected to a winch on a discrete trolley of the train.

Abstract: Apparatus for excavating ballast from a railroad bed and for cleaning the excavated ballast for return thereof to the railroad bed. The apparatus includes a vehicle for supporting a pair of excavating assemblies on opposite sides of the support vehicle and thus on opposite sides of the railroad track and a discrete cleaning station for each of the separate excavating assemblies. Each cleaning station is disposed for receiving and cleaning the ballast excavated by the associated excavating assembly. Each excavating assembly includes, in spaced, serial relation, a forward excavating wheel, an undercutter, and a second or rear excavating wheel.

Abstract: Railroad sleepers are replaced by removal of old sleepers over a track length corresponding to the length of a sleeper while ballast is removed to a depth corresponding to the height of new sleepers and is placed beside the track whereafter one or more new sleepers are lowered between the rails and rotated into correct transverse position followed by packing the ballast under the sleeper(s), and the space between adjacent new sleepers is packed with ballast.
