3. What is Ecp?

4. Electronically Controlled Pneumatics
ECP
Electronically Controlled Pneumatics
Cable based service and emergency brake control
Pneumatic emergency available via brake pipe
Monitoring of brake operation provided
Origin
Based on AAR S4200 cable based electronically controlled pneumatics for freight brake applications

5. ECP – NGEC origin NGEC Origin
During the development of the Bi-level technical specification, it was discussed if ECP brake control could replace the usage of the 26 C control equipment
Technical concerns were discussed that relate to passenger car operation that the AAR freight configuration would not address
Resolution – All NGEC technical specifications would state ECP ready
APTA agreed to develop the passenger ECP standards

6. What does ECP replace?
Replace existing 26 type brake control With next generation of ECP brake control

7. Why does passenger ECP need to be different?
Freight requires that the entire train be ECP equipped
Passenger ECP must be capable of working with conventional passenger brake control mixed in the same consist
Passenger equipment utilizes main reservoir pipe pressure for brake cylinder supply
The brake cylinder pressures used by passenger are different than freight

8. ECP benefits Provides state of the art technology for brake control
Maintenance intervals should be increased
Better train handling regardless of train length
Improved fuel efficiency for long trains such as Autotrain service
Train length no longer limited to 24 cars when the train is fully ECP equipment
Train brake status is displayed to the engineer

9. What is emulation mode?
Emulation Mode – allows the brake control to operate with the same characteristics as the 26 brake control
Utilizes the existing car battery for the power source rather than the ECP trainline cable
Allows the brake control equipment to be easily changed from ECP to emulation without a car level maintenance activity

14. Emulation test status
Four coaches (2 – NYAB and 2 – Wabtec) were equipped with passenger ECP brake control and tested to a modified Amtrak single car test
Static train test was conducted at the Penn coach yard with a existing locomotive and cab car.
Cars were then placed into the Keystone service (Harrisburg – New York)

15. Emulation test status
Four ECP Emulation Amfleet cars have been in revenue service for over 16 months (mileage as of 11/09/2015)
82610: 205,890 miles
82637: 200,224 miles
82629: 190,255 miles
82628: 186,622 miles
All cars have completed four 120-Day Preventive Maintenance intervals successfully
Failures
82610 failed control valve with failure analysis results of foreign contamination in the valve (not related to ECP components)
82628 failed ECP battery due to low battery voltage (identified product enhancement for passenger service to be incorporated in performance standard)
