MANUAL FOR LONG WELDED RAIL
MANUAL OF INSTRUCTIONS ON LONG WELDED RAILS
MANUAL OF INSTRUCTIONS ON LONG WELDED RAILS 1. DEFINITIONS 1.1 Long Welded Rail (LWR) is a welded rail, the central part of which does not undergo any longitudinal movement due to temperature variations. A length of greater than 250 metre on Broad Gauge (BG) and 500 metre on Metre Gauge (MG) will normally function as LWR (Fig. 1.1).

Short Welded Rails - BrainKart
Apr 08, 2016Short welded rails of three rail lengths (3 × 13 m for BG and 3 × 12 m for MG) have, therefore, been standardized on Indian Railways. 1 Track Specifications for Short Welded Rails . Indian Railways enumerates the following specifications for a track to be laid with SWRs.Author: Satish Chandra, M.M. Agarwal[PDF]

Production of long-welded and continuous-welded rail
Corus’ rail service centre in Scunthorpe which opened in 2007 is now capable of manufacturing long lengths of rail (108m) and producing 216m long welded strings which meet NR’s current policy of producing LWR with as few welds as possible. Following manufacture, these lengths of LWR are transported to site on a purpose-built train.

Track (rail transport) - Wikipedia
This is a manual process requiring a reaction crucible and form to contain the molten iron. Thermite-bonded joints are seen as less reliable and more prone to fracture or break.  North American practice is to weld 1 ⁄ 4 mile (400 m) long segments of rail at a rail facility and load it on a special train to carry it to the job
