In the late 1990s, working with KLD Labs, Loram developed the VISion Transverse Analyzer (VISTA), a computer guided grinding system. The VISTA system employs lasers to identify the rail profile and any defects. The computer then chooses an optimal solution, and guides the vehicle as it grinds the rail to this profile.

Why do welded rails not buckle?

One plate is placed either side of the rail and four bolts hold the plates and rail in place, with an expansion gap left between the rails. As the rail expands in warm weather this gap closes, and the gap is wide enough that on all but the very hottest of days the expansion can be accommodated.

Are train tracks hot after a train goes by?

Most railroad tracks are metal and when (most) metal heats, it expands. ... When the rails are already heated by weather, the added energy from the train traveling over the tracks can be enough to cause them to become too hot.
