Concept of Interchangeability

OCTYS is a program for renewal of Train Control Systems (CBTC):
based on the Interchangeability Concept applied to CBTC systems
for metro lines to be renewed in STO mode
OCTYS = Open Control of Trains, Interchangeable & Integrated System
i.e.: Interchangeable CBTC
OCTYS Contract signed in 2004 with 3 suppliers (ANSALDO, AREVA &
SIEMENS), for 5 lines to be revamped, in parallel with:
OCC modernization program
Rolling stock retrofit or renewal program
Signalling and Interlocking modernization program

Key challenges & lessons learnt
22
Key Challenge
To maintain good level of line availability
No service disruption during migration
Reliability of the new system since the start of the revenue service
Figures achieved
Line 3: CBTC OCTYS type 2 (w/o line capacity increase)
650 nights for system testing & commissioning (late arrival of a “system test bench”)
No service interruption
1 year to achieve an equivalent level of availability compared with legacy ATC
Lessons learnt
Test tracks, system test benches, and “shadow mode testing” are of utmost benefit
Possibility of long time tests without passengers on site to be valuable for availability (done
on UTO line 1)
STF, 2011/12/01
11
OCTYS CBTC project
Key challenges & lessons learnt
23
Key Challenge
Synchronize System migration with Signalling renewal and Rolling Stock replacement
Figures achieved
Line 3: CBTC OCTYS type 2 (w/o line capacity increase)
Signalling renewal late in terminus, leading to a “CBTC service limited to main
section of tracks: excluding of terminus” for 1 year.
Line 5: CBTC OCTYS type 1 (with line capacity increase)
Signalling works complexity not enough anticipated led to postpone system
deployment
=> New trains arriving, operated manually but needing to install a “simplified
trainborne equipment”.
Lessons learnt
Unlock signalling renewal program with CBTC installation (done for the coming next L9)
Anticipate system “minimum requirements” for operation of new trains before complete
CBTC deployment:
Allow for progressive migration strategies
Envisage “standalone” mode of operation for trainborne equipment
STF, 2011/12/01
OCTYS CBTC project
Key challenges & lessons learnt
24
Key Challenge
Minimize costs for CBTC
Figures achieved
CBTC OCTYS (L3, 5, 9, 10 & 12)
Open competition for 5 lines with a single specification,
contracted with 3 suppliers (interchangeability basis)
5 lines contracted for 100 M€2004 (CBTC only, excl. of ATS and
Signalling)
Lessons learnt
Standardize specifications as far as possible
Group (when possible) several lines in a single contract
Keep competition opened with several suppliers: interchangeability
STF, 2011/12/01
12
OCTYS CBTC project
Key challenges & lessons learnt
25
Key Challenge
Minimize impact on operating rules
Figures achieved
CBTC w/o line capacity increase (fixed block mode: OCTYS type 2 on L3 )
Stricly same op. rules but a great number of incidents linked to ergonomics factors.
As for ex:
Zero speed detection needs a delay (~1”) for the CBTC
: but drivers didn't use to wait that much before changing the master mode selector for
turn-back operation => EB applied
With CBTC, the minimum safety distance for approaching a stabled train is about 8m. This may
be reduced with a speed limit at 7 KPH: many drivers are tripped with this limit.
CBTC with Cab-Signal (OCTYS type 1 on L5)
Special care to be brought on the Cab-Signal ergonomics. This ergonomic constraint might
reduce some performances of the system (SACEM experience)
Lessons learnt
Consider ergonomics factors: a digital system actually does not react same as analog ones.
Extensive use of training simulators is of utmost benefit for smooth migration.
