Methods, systems and a kit for indicating brake air pressure status in brake pipes of multiple interconnected train cars are provided. The methods include operating at least one end-hose adapter per train car. Each end-hose adapter is mounted between a train car end hose and a brake pipe to be in fluid communication therewith and are configured to sense the brake air pressure in the brake pipe. Each end-hose adapter kit includes connections adapters for connecting either end to different parts of the train car system. The end-hose adapter provides a first visual indication when the brake air pressure is within an operable range and/or a second visual indication when the brake air pressure is below an operable value and is experiencing leakage.
