FIBER-TECH BETWEEN-CAR-BARRIERS (BCBs)*
a D.O.T./ F.T.A. mandate for “a safety device
between railcars to prevent individuals from stepping
off the platform between the cars and falling onto the
tracks”, Siemens Transportation Systems
and the Metropolitan Transport Authority called upon Fiber-Tech
Engineering to design & develop a working
solution for the requirement, to be installed on the Los
Angeles Light Rail – Green and Gold Lines. Fiber-Tech
Engineering designed and developed the completely
passive system, made prototypes and with evaluation by
STS and MTA including a full spectrum of testing, was
able to meet the design / performance criteria with success.
The BCB systems also met the rigorous requirements for
Flame/Smoke/Toxicity per MTA / STS specifications.
system consists of three, major components: HOUSING
(main exterior body), BASE PLATE (internal)
and the NOSE (extended from the Housing).
The Base-Plate and Housing are made of composite materials
while the Noses are made of cast Urethane elastomer. A
sub-system of Stainless Steel and Aluminum hardware is
employed for the assembly of the system. The NOSE components
form the actual ‘Barrier’ when parked at the
platform, yet survive continuous engagement when striking
each other as the cars go around turns on the tracks,
the unique Urethane elastomer material providing the compliant
fatigue and abrasion performance required.
