Transit Bus Market Products

Driver Protection Door

Vapor offers a Bus Operator's Door, which includes features that address operator comfort and safety. The purpose-designed door includes two integrated, high velocity electric fans for optimal air circulation in the cockpit area. An electrically operated window allows for increased air flow and ventilation and permits direct operator-passenger interaction. A heavy-duty, dovetail latch mechanism maintains positive contact to eliminate rattle. A large, laminated safety glass is contoured to allow direct visibility to mirrors. The door is custom designed for specific vehicles to ensure exact fit.

Dual Flow Valve

Vista Corporation has rebuilt over 3500 GE style water control valves. These valves include the dual flow used on 1987 through 1993 Dash 8's and the V1 and V2 used on the GE Dash 9 and AC4400 locomotives. All valves received are completely disassembled, cleaned, and inspected by our fully trained craftsmen. Valve bodies are re-plated back to original specifications. The actuator is overhauled; replacing all o-rings along with new bronze bushings and any other parts found to be defective during inspection. GE style water valves can be rebuilt to the GE specification, your specification, or Vista will be happy to suggest a rebuild guideline tailored to your specific needs to give you years of reliability.

Frost® Ground Contacts

The mechanical structure of our Frost® Ground Contacts meet effective national and international standards and directives. Material pairing is consistently optimized.
 
The design resp. working direction of the carbon brush is distinguished between axial and radial active contact system. Conventional round brush designs have been replaced by multiple brush designs in the area of standard applications. The reasons for this are, among others, the increased possible power transmission and in part, the simpler make-up of the contacts.  We have consistently continued to develop the successful path to multiple brush contacts and in the process, devised the successful frost® pressure system.

QBA15/QBA60

The QBA Series Air Dryer truly live up to the Quality Brake Air name. The QBA Air Dryers are equipped to fulfill the critical demands of the stop and go, high air usage, "Severe-Duty" vehicles. Unlike single tower devices, there are no restrictions as to how long a compressor can pump and no minimum compressor unload time is required. The QBA Series Air Dryers combine multiple high efficiency filtration components with twin tower drying technology in one easy-to-install, compact package. When properly applied, installed and with minimal maintenance, the QBA Series will literally transform your operation. Severe-Duty vehicles that have a history of winter brake air line freezing, heavy oil sludge, carbon, water and dirt can now enjoy the trouble free benefits of "Quality Brake Air".

SafeSet Lever Style Locomotive Parking Brake

Graham-White proudly introduces the SafeSet Locomotive Parking Brake. SafeSet is an automated electric motor driven system that also incorporates the standard manual interface found on lever style hand brakes. The primary operator interface is a control panel incorporating two push buttons: SET & RELEASE. In the event electrical power is unavailable, the operator simply uses the manual levers. In the manual mode of operation, SafeSet only requires 60% or less operator-input force than existing mechanical hand brakes.  Contact Graham-White to learn more about this exciting advancement in locomotive braking solutions.
