ATO now needs to orientate on the line

ATO today
For ATO positioning, magnetic balises type MIB-6 are used on SŽDC network:
In future, ETCS balises will be used instead

Target braking
What is driving with ATO like…?(Please wait for animated clip)
ATO AVV presentation 09/2009 17
Target braking
After closing the door driver pushes the Master Controller ahead…
ATO AVV presentation 09/2009 18
Target braking
…and holds it until the speed reaches 3 km/h.
ATO AVV presentation 09/2009 19
Target braking
Train driving is now controlled fully automatically.
ATO AVV presentation 09/2009 20
Target braking
Driver may check the ATO activity on the display (details see later).
ATO AVV presentation 09/2009 21
Target braking
Two horizontal bars above indicate required and real speed.
ATO AVV presentation 09/2009 22
Target braking
Below them, the area for target parameters is reserved.
ATO AVV presentation 09/2009 23
Target braking
We can see, that the braking curve to platform will appear.
ATO AVV presentation 09/2009 24
Target braking
This bar-like arrangement makes the comparison...
ATO AVV presentation 09/2009 25
Target braking
…between braking curves and real speed very easy.
ATO AVV presentation 09/2009 26
Target braking
Aside this area, the expected signal aspect is displayed.
ATO AVV presentation 09/2009 27
Target braking
On track with line transmission, it is derived from received ATP code.
ATO AVV presentation 09/2009 28
Target braking
Where is no line transmission, signal aspects are entered…
ATO AVV presentation 09/2009 29
Target braking
…using the keyboard below…
ATO AVV presentation 09/2009 30
Target braking
…which is used also for setting of required speed.
ATO AVV presentation 09/2009 31
Target braking
The vertical bar on right side indicates Proportional Traction.
ATO AVV presentation 09/2009 32
Target braking
As the real speed becomes equal the required one…
ATO AVV presentation 09/2009 33
Target braking
…the Proportional Traction decreases to maintain the speed.
ATO AVV presentation 09/2009 34
Target braking
Train is approaching the platform and the target braking begins.
ATO AVV presentation 09/2009 35
Target braking
The required speed starts to decrease…
ATO AVV presentation 09/2009 36
Target braking
…and the Proportional Traction grows to negative values.
ATO AVV presentation 09/2009 37
Target braking
Concurrently, the pneumatic brake of trailer coaches is used…
ATO AVV presentation 09/2009 38
Target braking
…because the dynamic brake alone is not capable to reach…
ATO AVV presentation 09/2009 39
Target braking
…the required braking deceleration, which is 0.8 m/s2.
ATO AVV presentation 09/2009 40
Target braking
Behind the window, we may already see the platform lamps…
ATO AVV presentation 09/2009 41
Target braking
…waiting passengers…
ATO AVV presentation 09/2009 42
Target braking
…and the End-of-platform board, which is the target now.
ATO AVV presentation 09/2009 43
ATO today
And now: how does the Energy Saving Device work…?
ATO AVV presentation 09/2009 44
Energy saving
Drive with us from Český Brod to Klučov. Our train departs just in time. (Please wait for animated clip)
ATO AVV presentation 09/2009 45
Energy saving
After departure, arrival time and name of next stop appears on display.
ATO AVV presentation 09/2009 46
Energy saving
As it is autumn morning and rails may be wet…
ATO AVV presentation 09/2009 47
Energy saving
…driver uses ATO´s feature for limiting of Proportional Traction (to 80%).
ATO AVV presentation 09/2009 48
Energy saving
Triangle markers below V-real indicate the speed to reach the platform in time.
ATO AVV presentation 09/2009 49
Energy saving
When real speed approaches the optimal one, coasting will be set automatically.
ATO AVV presentation 09/2009 50
Energy saving
The real speed is now 95 km/h, which accords to kinetic energy of 30 kWh.
ATO AVV presentation 09/2009 51
Energy saving
Without ESD, the train would accelerate to 120 km/h, which accords to 47 kWh.
ATO AVV presentation 09/2009 52
Energy saving
Thus, 17 kWh has been saved, which means approximately 37% saving.
ATO AVV presentation 09/2009 53
Energy saving
Meanwhile, see the parameters of three concurrent target braking processes:
ATO AVV presentation 09/2009 54
Energy saving
to track speed restriction from 130 to 120 km/h,
ATO AVV presentation 09/2009 55
Energy saving
to 3rd signal at STOP (expected signal sequence is Free –> Warning –> Stop),
ATO AVV presentation 09/2009 56
Energy saving
and to platform in Klučov.
ATO AVV presentation 09/2009 57
Energy saving
The train is still coasting without any traction power consumption.
ATO AVV presentation 09/2009 58
Energy saving
The regenerative braking may return part of kinetic energy back to catenary…
ATO AVV presentation 09/2009 59
Energy saving
…but on DC it crucially depends on other consumption in the area of substation.
ATO AVV presentation 09/2009 60
Energy saving
If there is none, the rheostatic braking is used instead of regenerative.
ATO AVV presentation 09/2009 61
Energy saving
Saying „part of energy“ we mean not only the efficiency of regeneration…
ATO AVV presentation 09/2009 62
Energy saving
…but also the fact that both electric and pneumatic brakes are applied.
ATO AVV presentation 09/2009 63
Energy saving
Due to limited power of electric brake, the regenerable part depends on speed:
ATO AVV presentation 09/2009 64
Energy saving
the greater is the initial speed, the less is the regenerable part.
ATO AVV presentation 09/2009 65
Energy saving
That´s why this driving strategy is the best, independent of use of regeneration.
ATO AVV presentation 09/2009 66
Energy saving
The train will stop now. Observe the arrival time, which should be 06:54:00…
ATO AVV presentation 09/2009 67
Energy saving
Just in time…

ATO AVV presentation 09/2009 73
ATO as executive system
Why did not we design ATO as an advisory system?
Driver need not pay any attention to follow any ATO´s instructions
Braking process is easily predictable, as the executive system performs it by itself
Thus, time accuracy is better, making the ATO more credible for driver
ATO AVV presentation 09/2009 74
ATO in numbers
In these days there are in regular operation with ASR+ATB+ESD:
50 double-decker suburban EMUs class 471 (next 10 in manufacturing)
250 km of equipped track 80 km of track should be newly
equipped in year 2009 28 subway trains type 81-71M with
derived ATO (Prague, line A, 12 km)
