Linsinger’s revolutionary MG11

On the right Track

Enter Linsinger’s revolutionary MG11 — the only reprofiling vehicle on the market that fits narrow Underground tunnels and reprofiles railheads in a single pass. The John Deere PowerTech™ 9.0L Final Tier 4/Stage V engine helps keep the Operation quiet.

Rail milling and grinding in a single pass

At 12 meters (39 feet) long, 2 meters (7 feet) wide, and 2.4 meters (8 feet) high, the compact MG11 rail-milling and -grinding train is only about the size of two large vans. Yet the unique, sleek design includes a 59-kilogram (130-pound) milling wheel that simultaneously scrapes the railhead. A grinding wheel then smooths the top of the railhead, removing running surface defects in a single pass.

The milling wheel can operate for up to four hours, depending on the condition of the track. The low pressure of the processing System reduces the risk of damage to the rails — an absolute must for transport authorities. Chips and dust are vacuumed right into an integrated tank, reducing harmful tube dust that is linked to allergies, asthma, and lung inflammation.

A quiet space

Linsinger was committed to sourcing an efficient and quiet engine for the MG11. Screeching trains, creaking wheels, and swirling gusts of dust contribute to harsh working conditions in subway tunnels. To give one example of the impact, a 2016 study of London Undergrounds sound levels by the University College London recorded a noise level of 109 decibels — louder than a helicopter taking off nearby.

The Company already had a great experience with an EWX 2.9L Final Tier 4/Stage V auxiliary generator set engine for a MG31 rail milling train delivered to Crossrail UK. For the MG11, the PSS 9.0L engine was the best choice. It not only met the Stage V emission Standard, but it also offered the right power-to-weight ratio. At a speed of 2000 rpm, the engine reaches 280 kW (375 hp). The John Deere engine powers all train functions, generating electricity and hydraulic power at fixed speed. Apart from hydraulic equipment to raise and lower the cutter heads, all drives are electric.
