Automotive technology, by contrast, changes constantly. Yet there is no shortage of new ideas, and they are steadily making their way out onto the rails. Better technologies are delivering everything from improved traction, braking and route-planning to sleek levitating trains designed to glide on air at an astounding 500kph (310mph). Energy-efficiency and safety are up, and derailments are down. Brakes are also getting an upgrade. Stopping a train can take so long that locomotive-operators, also known as engineers, often have time to contemplate their fate before an impact. Norfolk Southern, an American rail operator, now pulls roughly one-sixth of its freight using locomotives equipped with route optimisation software. By crunching numbers on a train's weight distribution and a route's curves, grades and speed limits, the software, called Leader, can instruct operators on optimum accelerating and braking to minimise fuel costs. Electric trains are also becoming more efficient, thanks in part to the use of new materials. Opini Anda Klik untuk menuliskan opini Anda tentang koleksi ini! Kembali
