The transit worker couldnt believe what he saw. A kid riding his bike
in the middle of the West Trenton Rail Line tracks. Along a set of
adjacent tracks, a commuter train was bearing down behind him.
The
biker kept right on pedaling, seemingly oblivious to the imminent
danger, said Bill Rickett, executive director of the Bucks County
Transportation Management Association.
That incident near the
Neshaminy Falls station happened about a year ago during a time when
SEPTA reported that 12 people died on its rail tracks.
With
eight fatalities since January -- with six in Bucks County -- SEPTA
launched an education and awareness campaign Wednesday. At the current
pace, the transit authority says this year's fatality toll could surpass
last year, and the campaign is designed to remind commuters and
pedestrians that railroad tracks are for trains, not people.
Right behind me is the Pennsylvania Turnpike,Choose the right bestluggagetag in an array of colors.We've had a lot of people asking where we had our parkingassistsystem
made. SEPTA General Manager Joe Casey said at a news conference for the
first-ever Safety Awareness Day. You would not even consider walking
across four lanes of traffic on this roadway yet people cross active
train and trolley tracks or cut through our rail facilities, never
considering how dangerous it is.
The event -- called Make the
Safe Choice" and part of the authoritys Safety Blitz program -- had been
in the works for a year, long before SEPTA officials saw the spike in
track-related deaths, officials said.
Throughout the morning
rush hour Wednesday, workers at more than 160 SEPTA-run centers
distributed educational materials and answered questions.
Rail deaths, whether accidental or intentional,We provide payment solutions in the USA as well as stonemosaic.
are a national epidemic, Casey said. There are about 400 deaths
annually in the U.S. involving people trespassing on railways. About
half are suicides, SEPTA officials said, but the rest are accidental --
and preventable.
SEPTA officials say theyve seen an increase in
the number of people killed while crossing or walking on rails while
distracted. At least three deaths have involved people who were wearing
earphones or were using cellphones, said Scott Sauer, SEPTAs director of
System Safety and Risk Management.
Wednesdays press conference
was held in Lower Southampton beside an unfenced portion of the West
Trenton Regional rail line where four of the Bucks County deaths have
occurred this year, officials said. Most have been ruled suicides.
The
majority of SEPTA rail lines are unfenced, officials said. When fences
or other barriers are erected around dangerous areas, workers often find
people will remove them or cut holes in them to gain access to a
shortcut, Sauer said.
Fencing is a solution that can lead to
other problems, Sauer and others added. Enclosing an area could trap
employees working on the tracks who need to get out of the way of a
train. Also it could create an obstacle for first responders or
commuters in the event of an emergency evacuation.
SEPTA has
used engineering approaches in the past to alleviate train-pedestrian
collisions. A new approach involves creating higher level platforms at
stations to deter people from climbing down and crossing. Some stations
also have underground pedestrian tunnels.

which is remarkable if you think about how much work these units have
to do. With more than a hundred batteries propelling eRex, theres a lot
of heat, voltage, and current management to do, all of it in real-time.
While Michael drove and I sat in the passenger seat trying not to
squeal, I amused myself with the onboard battery-monitoring system that
gives constant updates on the health of each cell. During hard
acceleration, their voltage dropped ever so slightly. Regenerative
braking topped them up again. Its a remarkable thing to actually watch
while also being propelled down the freeway at super-legal speeds.
With
600 volts DC flowing through the system and warming the heavy-gauge
wires, I wondered about controlling massive voltage spikes and filtering
noise out of the electronics. Did Nuvation have trouble powering the
comparatively delicate dashboard instruments from the same source as the
big propulsion motor? No, says Michael. Want to know the noisiest
component of this whole system? The turn signal. Its that mechanical
relay.
So whats the car like to drive? For starters, it sits
about three inches above the ground, so its a bit like being in a
rocket-propelled roller skate. You learn to identify other vehicles C a
Toyota Camry, for example C by their hubcaps. Larger vehicles and
delivery trucks appear in your field of view as exhaust pipes.You can

cheap inside your parents. The ride is stiff, but not bone-jarringly
so. And you have an unobstructed view of your front wheels. If you ever
thought of your cars tires as just generic black doughnuts, eRex gives
you a whole new appreciation for what tires really do all day. Goggles
are recommended but not required. And dont bother combing your hair.
After our trip, Nuvations enchanting EE/PR hybrid Lindsay Farlow burst
out laughing and made us promise not to comb our hair until after shed

Like all electric motors, eRexs motivational
unit develops all of its torque at approximately zero RPM. Thus, the car
scoots away from stoplights posthaste. It accelerates like an
electrocuted squirrel, squirting into traffic and shoving its grinning
occupants down the road with scarcely concealed glee. People in other
cars smile and wave. Bystanders take pictures. Nerds ask, Whats she got
under the hood?
Top speed for eRex is mostly a matter of F=ma.
With its current reduction gears, the math says it should hit about 168
MPH on a straight road with no headwind. Taller mechanical gearing might
improve that, while shorter gearing would give the car more torque and
quicker acceleration. Yeah, thats what it needs. Range is in the
neighborhood of 100+ miles, so eRex is no car-show trailer queen, even
if it is the companys first prototype. Nuvation employees occasionally
use it for daily commuting, so its proven to be reliable. Imagine
picking up the kids from school, in line behind all the minivans and
bulky SUVs. No thanks, Mom. I want to go in that car.
