San Diego MTS Implements
Early Warning Device
For Track Work
BY BRIAN RILEY

The EWD selected by MTS includes
three important elements: a Train Detection Module (TDM), Train Alert Module
(TAM) and Employee in Charge and
Watchperson/Lookout wearables.
The TDM can detect train or high-rail
equipment approaching a work zone.
The module is placed alongside the

The integration of EWD technology
into MTS RWPP required changes to
management procedures through Rule
Book, Standard Operating Procedure and RWPP manual revisions. All
RWPP employees received specific
training including "Rule of the Week"
for train operators and flagmen. MTS
also has added an EWD module to

As a train approaches the TDM, flashing lights alert the train operator. The TDM is placed 15 seconds prior to the train arriving at the work zone. The train passes over the TDM, activating the TAM

* Start the procurement process
early. Understand that procurement often takes longer than
expected.
* Involve a team in the analysis

remain the primary means of roadway
worker safety. EWDs do not replace
them or diminish their importance. But
the EWD system provides an additional
layer of protection above and beyond
those preexisting requirements.
By early November 2019, MTS had
finished implementing the EWD program for all its roadway worker restrictions, providing an added layer of safety
for vulnerable workers along the rail
system.

* Be sure to budget accordingly. A public transit agency
may need more than one
budget cycle to accrue the
appropriate financing for
EWD systems. MTS' cost
for implementation was
approximately $590,000
for 36 complete sets, each
including two TDMs, four
TAMs, three wearable
devices and a battery pack.

operations, rail and bus operations,
maintenance and track allocation, as
well as capital planning and delivery,
has provided me with wonderful opportunities to participate in real change in
an industry that is moving forward fast.
Technology advancements have been
game changers in our business. Data
tools have reduced safety risks. Safety
management systems now identify hazards and track trends. Deploying equipment that prevents injuries has also
produced a return on investment.
Working in a Rail Control Center
for many years, I never
imagined that a controller would be able to see
the same faults that the
operators can see, in real
time, on the train condition
data display. Having the
ability to use the information to troubleshoot and
reduce the delay time is
significant.
Reliability centered
maintenance processes
have enhanced the useful

life of our equipment and productivity.
One series of cars in our WMATA rail
fleet has now traveled more than one
million miles without a recordable delay
of less than three minutes.
Using available data from passenger
travel times has allowed us to successfully commit to our passengers during
rush hour that we "Promise" to deliver
them to their rail destination within

10 minutes of the scheduled trip time or
their fare is credited for future travel.
This service guarantee-delivered
automatically to customer accounts
within a day-not only was a new
WMATA commitment to riders, it
changed the way we think internally.
