The SludgeBraker® model QBA15 is equipped to fulfill the critical demands of inner city, stop and go, high air usage, “Severe-Duty” vehicles. Unlike single tower devices, there are no restrictions as to how long a compressor can pump and no minimum compressor unload time is required. The QBA15 combines multiple high efficiency filtration components with twin tower drying technology in one easy-to-install, compact package. When properly applied, installed and with minimal maintenance, the SludgeBraker will literally transform your truck or bus operation. Severe-Duty vehicles that have a history of winter brake air line freezing, heavy oil sludge, carbon, water and dirt can now enjoy the trouble free benefits of "Quality Brake Air".

Track Data Management

In order for the I-ETMS System to traverse a route it needs to be aware of all the potential stop targets and operation rules on that route. A track database in the form of a SubDiv file provides the I-ETMS system with all the geographic geometry and attribution needed to identify stop targets and attributes. The track database also provides operating rules and speeds as additional information for the I-ETMS to determine the correct behaviors required for that route and track. Wabtec provides tools and services to create the track database and SubDiv file for the I-ETMS system. The intent of this document is to define the services we provide within the PTC space.
