Claim 8

An air brake testing device for a 26-L locomotive air brake system having a compressed air source, conduit means for the ingress and egress of compressed air and a brake valve which is communicatively connected to both the compressed air source and to the ingress and egress conduit means of the 26-L air brake system, said testing device being primarily for testing the functionality of the brake valve of the brake system, said device comprising: a. a storage reservoir essentially for holding compressed air and having a volume which is generally equal to a volume of a braking system for a predetermined number of rail cars, b. a trackside stand having a conduit with opposing ends, one said end being communicatively connected to said storage reservoir and said opposite end having connecting means and being communicatively connectable to the ingress and egress conduit means of the 26-L locomotive air brake system, c. air pressure testing conduit means having a pressure gauge and having connector means for insertion between said trackside stand conduit and the ingress and egress conduit means of the locomotive air brake system, and d. a flexible testing conduit with opposing ends, each end having connector means attached thereto, said flexible testing conduit for insertion between said trackside stand conduit and the ingress and egress conduit means of the locomotive air brake system to communicatively connect said storage reservoir to the air brake system, whereby, the communicative connection of said connecting means of said trackside stand conduit to the ingress and egress conduit means of the 26-L locomotive air brake system by means of said flexible testing conduit, permits the operability and functionality of the locomotive air brake system to be tested by said testing device at said trackside stand by causing the flow of compressed air of the locomotive air brake system to and from said storage reservoir without the requirement of having to actually communicate the locomotive air brake system to a number of rail cars of a predetermined number, and, whereby, subsequent to the communicative connection of said connecting means of said trackside stand conduit to the ingress and egress conduit means of the 26-L locomotive air brake system additionally permits the testing of the accuracy of the locomotive air brake system air pressure gauge.

Claim 9

An air brake testing device for a 26-L locomotive air brake system having a compressed air source, conduit means for the ingress and egress of compressed air and a brake valve which is communicatively connected to both the compressed air source and to the ingress and egress conduit means of the 26-L air brake system, said testing device being primarily for testing the functionality of the brake valve of the brake system, said device comprising: a. a storage reservoir essentially for holding compressed air and having a volume which is generally equal to a volume of a braking system for a predetermined number of rail cars, b. a trackside stand having a conduit with opposing ends, one said end being communicatively connected to said storage reservoir and said opposite end having connecting means and being communicatively connectable to the ingress and egress conduit means of the 26-L locomotive air brake system, c. air pressure testing conduit means having a pressure gauge and having connector means for insertion between said trackside stand conduit and the ingress and egress conduit means of the locomotive air brake system, and d. a flexible testing conduit with opposing ends, each end having connector means attached thereto, said flexible testing conduit for insertion between said trackside stand conduit and the ingress and egress conduit means of the locomotive air brake system to communicatively connect said storage reservoir to the air brake system, whereby, the communicative connection of said connecting means of said trackside stand conduit to the ingress and egress conduit means of the 26-L locomotive air brake system by means of said flexible testing conduit, permits the operability and functionality of the locomotive air brake system to be tested by said testing device at said trackside stand by causing the flow of compressed air of the locomotive air brake system to and from said storage reservoir without the requirement of having to actually communicate the locomotive air brake system to a number of rail cars of a predetermined number, and, whereby, subsequent to the communicative connection of said connecting means of said trackside stand conduit to the ingress and egress conduit means of the 26-L locomotive air brake system additionally permits the testing of the accuracy of the locomotive air brake system air pressure gauge.
