Clements National’s Cadillac brand of 27-point
jumper assemblies and receptacles are available
in a variety of configurations for trainline (COMM)
car control/communication and (MU) multiple unit
locomotive control.
Car control/communication trainlines are
interconnected between the entire length of the car.
Typical electrical signals include: door controls and
indications, public address, brake applied/released
indications. Multiple unit trainlines carry traction and
dynamic brake commands and indications. Typical
signals between equipment include:
– Locomotives coupled together
– Cab car and locomotive
– Locomotives or power cars placed
at opposite ends of the train
Design Benefits:
• Manufactured to conform to AAR S-512 and
APTA RP-E-019-99 specifications.
• Qualified for use on all Amtrak equipment, as well
as other major transit agencies.
• Self aligning silver plated copper socket contacts
permit low mating forces, prevent excessive voltage
drop and promote long contact life.
• Interchangeable and intermateable with other
major brands
• Environmentally protected design with individual
contact seal boots and outer “O” ring seal on front
dielectric to connector body.
• Unique “multi-contact” band design on pin contacts
provides reliable electrical engagement and is field
serviceable and replaceable without removing
connector from train.
