The DT railway fastening system, with its unique performance characteristics, has been widely adopted in urban rail transit systems, serving as critical infrastructure for metro and light rail lines.
In main metro lines and branch routes, this system demonstrates exceptional performance. Shanghai Metro Line 1's general vibration reduction sections employ DTIII fasteners, where the two-stage elastic design effectively reduces vibration transmission, minimizing impact on nearby residents. Beijing Metro's selected lines utilize DTI fasteners that adapt well to the humid and dusty tunnel environments, with rust-proof metal components and stable insulation performance ensuring proper track circuit operation - meeting the demands of high passenger volumes and dense train schedules.
Light rail networks represent another crucial application. As these lines often traverse urban built-up areas requiring superior vibration and noise reduction, the DT system's dual-layer elastic pads provide 5-10dB vibration attenuation, perfectly matching light rail's environmental requirements. Its flexible gauge and vertical adjustment capabilities accommodate potential subgrade settlement issues, maintaining precise track geometry for safe train passage.
The system also plays vital roles in metro depots and test tracks. Frequent train starts/stops in depots demand exceptional fastening stability - the system's consistent spring clip pressure ensures secure rail fixation. Test tracks simulating various operational conditions benefit from the system's precise adjustability, guaranteeing track parameters meet testing standards for reliable rolling stock performance evaluation.
Furthermore, the DT system has been selected for urban regional railway projects, particularly in underground sections and ground-level vibration reduction zones, owing to its strong adaptability. It serves as a dependable solution for rail connections between urban cores and suburban areas, providing robust support for smooth urban public transportation operations.
