You
may have seen more LANta diesel hybrid electric buses on the roads of the
Lehigh Valley since Monday, February 24, 2014. Of the 83 buses in LANta’s bus
fleet, twenty-four (24) are now the newer, lower emissions, diesel hybrid
electric buses. Each hybrid bus stands
out from the non-hybrid, diesel buses with a raised area towards the rear of
the roof. This houses the batteries, the control module for the hybrid
propulsion system and cooling fans for the system.
These
new buses were purchased through the Pennsylvania State Consortium program that
was led by Red Rose Transit Authority (RRTA) in Lancaster. RRTA led a group of
17 transit agencies from across Pennsylvania to collect bids for the purchase
of 200 buses over a multi-year period. By entering into a joint purchase, the
transit agencies involved were able to obtain more competitive pricing. So far, LANta has purchased 19 buses through
the program and plans additional purchases based on available funding. The cost of a diesel hybrid electric bus is
just under $600,000, where the cost of a standard diesel bus is just under
$400,000. However, this price difference is recouped over the first 9 years due
to the hybrid vehicles getting over a 50% fuel efficiency compared to standard
diesel buses. LANta anticipates using each bus for 13 to 15 years.
The
buses were purchased from Gillig Corporation in California. Five of the new buses are 35’ in length and
four are 40’. The 2014 buses are very
similar to the 2012 hybrid buses except for a few upgrades; there is a new and
updated hydraulic system along with updated passenger straps for the wheelchair
stations. After the buses come off the factory line, each is driven from
California to our site in Allentown. Roughly 3,000 miles are on the bus when it
arrives. This lengthy drive is a good test to make sure systems are running
properly. The long drive also provides a
good “break-in” for the vehicle.
When
the buses first arrive it is necessary to install additional equipment needed
for revenue service. A week is spent on
each bus installing the farebox, two-way radio and the Automated Transit
Management System (ATMS).
As
noted above, LANTA has experienced a 50% fuel efficiency gain with these
vehicles over the standard diesel powered buses in the fleet. Based on this experience and LANTA’s current
usage in terms of miles per bus, it is anticipated that using diesel hybrid
electric buses results in a reduction of approximately 2,780 gallons of diesel
fuel needed to operate each LANTA bus annually.
It is estimated that the use of these buses will benefit air quality in
the region by reducing NOx, a component of ozone, by -1.9350 kg/day per bus.
These
nine new diesel hybrid electric buses will replace 1998 New Flyer buses which
have been in service for 16 years. On
Monday, February 24, four of the new buses were put into service, Tuesday,
February 25 two more were entered into service and it is expected that by
Friday, February 28, all will be in service.
