The valve can operate as a conventional air brake or in ECP mode with wired or radio control.

Korean-built trainsets for the third phase of the Seoul metro are being equipped with torque reaction links from the Silentbloc Division of Silvertown UK, as part of two contacts under which Alstom Gears Ltd is supplying 660 traction gearboxes to Hyundai for the Line 6 fleet and 770 to Hanjin for the Line 7 cars.

Precision sensing for determining straightness, flatness, twist, bow and camber of rails is provided by the latest ML-2100 measurement system, developed by Milburn Research Solutions Inc of Nova Scotia. The non-contact system can provide profile measurements over long distances to an accuracy of 0·0025mm without a precision straightedge for reference.
