A number of incidents of compressed natural gas (CNG) cylinder leaks have occurred while transit buses were either in service or at a bus maintenance facility. This study was initiated to determine the degree to which cylinder problems still exist in the field and the status of their resolution. A letter requesting information was sent to 41 transit agencies, and 28 responded. The study identified the types of compressed natural gas and liquefied natural gas (LNG) cylinders that are being used on transit buses, and the problems being experienced with them. The study assesses the magnitude of these problems, and remedial actions being taken by the transit industry.
