Our achievements
«Petersburg Tram-Mechanical Factory» OJSC («PTMF» OJSC) –
leader in developing of new tram-car models in Russian
Federation. The first six-axle car with low floor quantity
more than 60%, the first low-floor eight-axle one-way and
double-way (shuttle) cars with asynchronous motor drive, the
first four-axle car with 40% of low floor quantity – all
comprises the production of our factory.
The most significant achievement of late years was
development and producing of new tram-cars models: 71-152,
71-153, 71-154 è 71-154Ì.
In December, 2006, «PTMF» OJSC finished test series for
model 71-152 (LVS-2005) car and, by inter-departmental
committee’s decision it was officially approved for
exploitation on St. Petersburg’s streets. LVS-2005 – the
first Russian six-axle articulated car with low floor
quantity more than 60%, and corresponding to low floored
cars of European level. On its base may be built four-, six-,
and eight-axle cars for both-way traffic. The numerous
novelties in this tram-car comprise modern appearance,
improved saloon interior, the use of power-saving electric
drive, reduction of total car’s mass and, as a consequence,
its operation cost (including electric power), as well as
capability of moving in autonomous mode, and advanced
control methods (from on-board computer to joysticks for
side mirrors adjusting). The emphasis falls on the needs of
passengers with push-carts, disabled persons and pensioners
– the cars provide wide doorways and accumulation platforms
in low floor parts of the tram-car, where the floor height
for mounting equals 35cm. The modular build of cars enables
the use of LVS-2005 both for city tramlines exploitation and
in projects for developing light rail-tracked transport (LRT)
systems, meant for Russian and foreign cities. On May 5,
2007, «PTMF» OJSC received an official notice from FGU («Federal
institute of industrial property of federal agency on
intellectual property, patents and trademarks”) (ROSPATENT)
with decision concerning granting of a Patent on Useful
Model – “TRAM-CAR”, claim ¹ 2007113838/22 (015020). This
event marked off the final act in more than one-year work of
engineering, technologic, and other factory subdivisions,
involved in designing articulated car of new generation,
model 71-152, with elevated occupancy (LVS-2005). This
tramcar passed all the acceptance trials complex including
test run, then was accepted by inter-departmental committee,
appointed by Ministry of Transport of Russia, and in May,
2007, placed on balance of Saint Petersburg’s «GORELEKTROTRANS».
In conformity with government contract, by the end of 2007
on St. Petersburg lines appeared in all 5 low floored
six-axle cars «PIONEER», model 71-152, with elevated
occupancy. Now in streets of Northern capital 25 trams of
the given model are already maintained.
In accordance with acting on «PTMF» OJSC Development
Program, providing the possibility of model series widening
for challenging product, at the end of 2007, on the base of
engineering solutions realized in six-axle tram-car (model
71-152 «PIONEER»), was made one-car version of four-axle
tram-car LM-2008, model 71-153. On May 15, 2008, the factory
completed, according to plan, a trial complex of this car,
and then it was officially approved by Inter-departmental
Committee (IDC) for exploitation on city’s streets. LM-2008
is a new 4-axle car with 40% low floor quantity. This car
appears as the second stage in designing model series of new
generation tram-cars produced by «PTMF» OJSC on the base of
serial low floor car with elevated occupancy. New car’s
design and its main elements resemble the familiar to St.
Petersburg’s passengers tram-car «PIONEER» (LVS-2005). In
summer 2008 this tram was presented to city authorities and
in the second half of the year serial production of the car
commenced. In the beginning of December 2008, «PTMF» OJSC
completed two 71-153 (LM-2008) cars for «Gorelectrotrans»
SUE (Saint Petersburg). This model is now running in four
cities of the RF.
One more achievement of 2008 became working out and
manufacture of the tram car of model 71-154 (LVS-2009). This
model is a custom-built tramcar specially designed by «PTMF»
OJSC for Volgograd streetcar express system (Metrotram)
pursuant to the municipal contract for delivery of two
express tramcars signed in June 2008. Tramcar express is an
advanced transportation system featuring improved
transportation capacity, high car speed and enhanced safety
achieved by a unique customized design of the street railway
and vehicle itself according to a special technology.
Although tramcar express is a technical continuation of
regular streetcar system, it requires new spacious low-floor
cars with sufficient number of doors and two cabs for
two-way shuttle runs. As it was scheduled, on December 10,
2008 «PTMF» OJSC completed complex trials of 71-154 tramcar
and the Interdepartmental Commission recommended it for
serial production. 71-154 (LVS-2009) tram is a unique
vehicle designed and manufactured by Saint-Petersburg
streetcar makers and continues the series low-floor
high-capacity trams by PTMF. Eight-axle three-unit car
designed and manufactured in the shortest possible time
combines cutting-edge technologies with seasoned technical
solutions, components and materials that proved to be
efficient in 71-152 and 71-153 models. The main difference
between 71-154 and the previous models is that it may be
used for two-way (shuttle) runs as it has two operator’s
cabs and does not require turning circles in the end of the
route. Passenger can enter and leave the car from either
side depending on the location of platform. Elevation of the
low floor of new PTMF cars is 350 mm.Low-floor share in
71-154 is 43%.Wide door openings on both sides of the car as
well as passenger areas in the low-floor sections were made
to speed up entraining/detraining process and improve
transportation conditions for disabled persons and
passengers with baby buggies.A standard car layout includes
50 seats and also contributes to enhanced transportation
conditions.The car has eight 90 kW rotary field motors used
to comply with the traction and power requirements set out
by technical norms and regulations for tunnels with
increased air drag.Multi-purpose bogie uses two-stage
springing system and vibration damping rubberized 6230 mm
BonaTrans wheels and provides 750 mm elevation compared to
900 mm elevation typical for streetcars currently
manufactured in RF. In case of any failure, each car can
move without exterior traction as it has four independent
traction drive mechanisms - one four each bogie.It can move
using three, two or even one bogie.Traction drive system is
equipped with so-called blackbox used to collect video
information related to the performance of traction drive
systems.The car has an automatic locomotive alarm system
designed to ensure automatic speed correction and perform
interval train correction (ALS-ARS-ST). Ëîáîâûå è áîêîâûå

interior panels are made of polymer materials that eliminate
corrosion and extend service life of the car body. Advanced
electric braking system keeps stopping distance within the
set value, whereas mechanical brake applies at zero speed,
thus minimizing brake shoe wear. Car anti-slipping and
anti-skidding systems reduce rail impact and make slowdown
process controllable under any circumstances. The car is
equipped with hill holder system helpful at starting the
tram on a slope. The car is equipped with the Lincoln
automatic centralized lubrication system that minimizes
maintenance efforts and ensures high-quality and timely
lubrication of the car components and, therefore, extends
service life of parts and mechanisms.The major appliances
are placed on the car roof and in the technical compartment
of the cab. The car wiring was accomplished using Harting
connectors, which ensure highly reliable connections, smooth
and easy interconnection and disconnection made within the
circuit, minimize likelihood of incorrect assembly and do
not require any maintenance. The car uses two collecting
pantographs with electric drive by LEKOV Czech Company and
modified and forced carriage adopted for overhead contact
system currently used in Russia (overhead wiring load – 70
to 110N ± 10 N). Two Hubner coupling sets are installed on
the car. The interior of the car is decorated with several
lines of luminous tubes equipped with high power electric
blower heaters used for its heating and ventilation, audio
information system, scrolling text information panel and
emergency door opening system. Additional fresh air inflow
is achieved by the four roof hatches with built-in fans. The
car is built with Tamware doors equipped with
injury-preventing mechanism and anti-jam function.
Operator’s control panel is based on the automated computer
system with touch screen display. Video control system helps
the operator to monitor the car and the driveway. Moreover,
the blackbox of digital video surveillance system records
video information that may be later extracted and analyzed
and become helpful in case of accident or incident. Air
conditioning system maintains required level of comfort and
microclimate in the operator’s cabs. Two 71-154 cars are
successfully operating on Metrotram lines in Volgograd.
In August 2009, PMTF OJSC completed its latest model -
71-154Ì. 71-154Ì – is an 8-axle street car with asynchronous
motor drive. A new product from PMTF low-floor model range,
it was designed by Saint-Petersburg car builders in 2009.
Therefore, having developed this class of tramcar the plant
approached to construction of light rail transport (LRT). It
was development of tramcar expresses projects that
encouraged discussion on this mode of transport in Russia.
Today, such projects are developed not only in Saint
Petersburg, but also in Moscow, Voronezh, Volgograd and
other cities.
In Russia, there are yet no analogues to the cars, built
at «PTMF». As a result of carried out work, it may be
definitely said that «PTMF» OJSC have in its sales portfolio
two modern base models of tram-car, that can satisfy the
requirements of any Russian city, be it a megalopolis or a
town.
