• Description:
  Transportation Technology Center, Inc. (MxV Rail), in collaboration with a railroad technical advisory group (TAG), through Federal Railroad Administration (FRA)-funded research and proof-of-concept field testing with a supplier’s equipment, found that a Virtual Block Track Circuit (VBTC) concept has the potential to reduce train headways and increase rail network capacity. The VBTC concept uses track circuit-based detection methods to divide conventional physical signal blocks into multiple virtual blocks, without adding wayside devices at virtual block boundaries or modifying the current Positive Train Control (PTC) onboard system.
