MxV Rail (formerly TTCI) compared the ballast compaction ability of a truck-based Dynamic Track Stabilizer (DTS) against accumulated tonnage under speed restriction in a heavy axle load (HAL) environment. Two tie types and DTS down-pressures were evaluated both in terms of lateral tie resistance and with short- and long-term track settlement. The loosening of ballast particles during tamping and other ballast maintenance activities can reduce the ballast particle interlock strength and, thereby, reduce lateral track strength. This increases the risk of track buckling in continuously welded rail (CWR) track, and trains are typically put under a speed restriction (also known as slow order tonnage) until the ballast compacts. Ballast compaction can occur in one of two ways: through train tonnage (typically the first 0.1 MGT) or through vibratory compaction using a DTS. If a DTS is used following surfacing, the number of trains requiring speed restrictions is significantly reduced from…
