Insulated joints growing independently of continuous welded rail conversion
Track circuit signalling detects trains by passing current along the rails, which requires an electrically isolated break at every block boundary regardless of how much of the intervening track is welded. Insulated rail joints therefore survive conversion programmes that eliminate every other joint on a route. They grow at 6.3%, half again the market rate of 4.2%, and they carry engineered glue lines, bonded plates and signalling approval rather than the commodity economics of a plain forged plate. Replacement intervals near seven years on heavy axle routes make them a consumable rather than a fitting.
