ATM rolling stock (surface service)

• ATM manages both surface and underground urban
  and inter-urban transport service, besides other
  special services.

As far as surface service is concerned, the ATM
rolling stock is now composed by - 421 trams, -
1517 buses, - 148 trolley-buses.
3
Current ATM tramway service

• 18 lines with a total extension of 164,4 km
  (double track)
• 14,1 million km per vehicle per year

4
2001 development

• Line 14, with a length of 14,4,was fully
  refurbished and the service started at the
  beginning of the year 2001.

5
Recent developments
This branch opened in Dec. 2003, 2,1 km, with 800
m in tunnel
North, opened in Dec. 2003, 8,5 km
29 / 30, is being refurb. and the service will
start in Dec. 2004, 13,0 km
Cinisello, the service will start in Dec. 2005,
10,9 km
South, opened in Dec. 2003, 10 km
6
New line main characteristics

• maximum independent way (it isnt easy to obtain
  it in Milan due to the narrow roads)

7

• Platform with two different levels to match all
  kind of ATMs trams

• first part at 180 mm on T.O.R. for old trams
• second part at 220 mm for more recent trams,
  using ramps in case of low floor trams or second
  part at 280 mm for low floor trams, where their
  ramps cant operate.

8

• Stops with
• Time table
• Radio controlled public information system to
  give service information to passengers
• Lights
• Seats
• Information maps

Electronic traction and auxiliary converters

• At the state of art through
• Asynchronous traction motors,
• IGBT converters (for traction and auxiliary)
• Energy saving by recovery braking.

22
Electronic control and diagnostic

• Based on microprocessor units distributed along
  the vehicle and European standard bus lines
• Advanced on board diagnostic with the possibility
  to introduce maintenance experience
• Redundancy of the main devices in order to limit
  service breakdown in case of failure.

23
Boarding
Easy boarding and alighting specially for eldery
person and mobility impaired people thanks to
floor completely at 350 mm on T.O.R.

SafetyCrash

• Good crash behaviour in order to protect driver
  and passengers

• Body shell compressive strength gt 350 kN
• Heads that can absorb, with ELE 4, impacts
  against a fixed obstacle
• Elastically until 4,5 km/h
• Plastically until 15 km/h with integrity of
  drivers cabin.

27
SafetyDead Man device

• Button on driving lever to press during the run.
• Otherwise
• 2 s acoustic alarm
• 4 s safety brake

28
SafetyStatic Event recorder

• To record all important signals during service
  (position of driving control, speed, dead man
  state, doors state.)

29
SecurityVideo control system

• Internal cameras
• Hard disc recorder with more days capacity - 3
  frames per second
• Video control for the driver

Camera
30
CommunicationAutomatic vehicle Monitoring

• Communication between driver, passengers and
  central control room
• Alarm
• Automatic calculation of on board passengers
• Next station announcement
• Tram Localization in Central Control Room and
  Waiting time information at stops.

31
Fire behaviour

• Components used for the production comply with
  metro train regulation (trains running in tunnel
  with safety evacuation time between 15 and 30
  minutes) to maximize the rolling stock safety.

These materials limit the risk of fire
propagation and the toxicity, opacity and
corrosiveness of emissions.
32
Preliminary test

• Preliminary test on prototype vehicles
• Strasbourg Eurotram has been tested for 2 months
  in Milan
• Sirio prototype has been tested for 9 months in
  Milan.

Particular attention was paid to the air
conditioning device, traction and auxiliary
equipments

• A 1928 type tram was equipped with shapes to
  simulate Eurotram and Sirio maximum gauge in
  order to evaluate the condition of the old part
  of the network.
