Patent
CA 2370807
An integral intermodal train is provided for carrying standard over-the-highway semi-trailers. Each segment can have a plurality of platforms and may be loaded or unloaded independently of any other segment using a self contained, roll- on/roll-off system. Several sub-systems to speed performance and enhance reliability, such as an electronic assisted air brake, health monitoring, trailer tie-down and locomotive interface subsystems, can be provided on each segment. A spring applied parking brake is provided for the segments and operably connected to the train pneumatic brake systems. In a preferred embodiment the brake is automatically applied when brake pipe pressure falls below 40 psi nominal. The pneumatic valving for the parking brake prevents application of the valve in an emergency braking situation; until the pressure has bled off in normal system leakage, preventing wheel damage. A handle is provided for manual application and release of the parking brake when desired.
