LRG

Transit Rail Grinding

Versatility and performance for transit lines.

The Loram LRG Series Transit Rail Grinder is a compact solution designed for production rail grinding on transit railroads and specialty rail grinding on any railroad. The LRG features technology and the same highly-productive 23 kW grind motors from our heavy haul mainline grinders, in a smaller footprint design to navigate a variety of transit, short line and Class I railroads – including those with curve radius, clearance and weight restrictions.

The LRG is able to grind a variety of common rail conditions, including corrugation removal, mill scale removal on new rail, switches, crossings, imbedded rail, tunnels, open rail spots and rail head profiling. Advanced grind quality control systems provide a positive means to address only the high spots associated with corrugation, welds and other defects, while bridging the low spots.
