Abstract
Abstract A mobile track renewal apparatus comprises a frame mounted on undercarriages for mobility on the replacement track in an operating direction during track renewal. Carrier arms extend forwardly and rearwardly from the mobile frame and respectively receive the new and old rails, the carrier arms being vertically and laterally adjustable in relation to the frame and fixable in a selected adjusted position. Similarly adjustable and fixable guides are mounted on the frame for guiding and laying the new rails.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
187 words
In a mobile track renewal apparatus for concurrently receiving an old rail of an existing track and laying a new rail of a replacement track, which comprises a frame mounted for mobility on the replacement track in an operating direction during track renewal, a carrier arm extending forwardly in the operating direction from the mobile frame, the carrier arm being adjustable vertically and laterally and being fixable in a selected adjusted position, means laterally of the frame and carrier arm for receiving the old rail, the rail receiving means being mounted on the frame for movement along the rails, and means mounted on the frame for guiding and laying the new rail, the rail guiding and laying means being adjustable vertically and laterally and being fixable in a selected adjusted position: a further carrier arm extending rearwardly in the operating direction from the mobile frame, the further carrier arm being adjustable vertically and laterally and being fixable in a selected adjusted position, and means on the further carrier arm for receiving the old rail from the laterally mounted rail receiving means and for guiding the old rail.
Claim 2
Dependent Claim
187 words
In a mobile track renewal apparatus for concurrently receiving an old rail of an existing track and laying a new rail of a replacement track, which comprises a frame mounted for mobility on the replacement track in an operating direction during track renewal, a carrier arm extending forwardly in the operating direction from the mobile frame, the carrier arm being adjustable vertically and laterally and being fixable in a selected adjusted position, means laterally of the frame and carrier arm for receiving the old rail, the rail receiving means being mounted on the frame for movement along the rails, and means mounted on the frame for guiding and laying the new rail, the rail guiding and laying means being adjustable vertically and laterally and being fixable in a selected adjusted position: a further carrier arm extending rearwardly in the operating direction from the mobile frame, the further carrier arm being adjustable vertically and laterally and being fixable in a selected adjusted position, and means on the further carrier arm for receiving the old rail from the laterally mounted rail receiving means and for guiding the old rail.
Claim 3
Dependent Claim
66 words
In the mobile track renewal apparatus of claim 1, undercarriages supporting the frame for mobility on the replacement track, the distance between the rail receiving means on the forwardly extending carrier arm and a next adjacent one of the undercarriages being substantially the same as the distance between the rail receiving means on the rearwardly extending carrier arm and a next adjacent one of the undercarriages.
