Claim 6:
7. A braking system onboard a vehicle system having vehicles in a first segment and a second segment, the vehicles in the first segment including a lead vehicle and a remote vehicle, the vehicles in the second segment including a first vehicle that is adjacent to the remote vehicle in the first segment, the braking system comprising:
a brake pipe configured to fluidly couple air brakes disposed onboard the vehicles in the first segment and in the second segment;
a cable extending through the first vehicles in the first segment; and
electronically controlled pneumatic (ECP) control devices configured to be disposed onboard the vehicles in the first segment, the ECP control devices configured to control operation of the air brakes onboard the vehicles in the first segment,
the ECP control devices configured to receive an electronic command signal conducted along the cable that actuates the brakes in the vehicles in the first segment, wherein the air brakes in the vehicles in the second segment are not actuated by electronic signals,
the ECP control device onboard the remote vehicle in the first segment configured to receive the electronic command signal and create a reduction in air pressure in the brake pipe in the first vehicle in the second segment that is adjacent to the remote vehicle, the brake pipe configured to pneumatically communicate the reduction in the air pressure as a pneumatic command signal to the air brakes onboard the vehicles in the second segment that actuates the air brake in the vehicles in the second segment.
