MP 89

MP 89 designation

Record the evidence identifying a candidate as MP 89 and distinguish that designation from its individual fleet number.

1. Which vehicle marking or authoritative technical record identifies this candidate as MP 89? provenance
2. Does the supplied identifier denote the MP 89 family, a variant, a car or a complete trainset? boundary

Variant and driving arrangement

Associate CC or CA identity with documented cab arrangements and operational responsibilities.

1. Which records establish CC or CA identity, and which physical control arrangements corroborate it? definition
2. Does evidence describe the train's variant or merely an automatic driving function fitted to it? boundary

Approved car composition

Record car count, ordered roles and dimensional evidence without assuming that every MP 89 retains its original formation.

1. What car count and sequence are approved for this MP 89 variant and modification baseline? definition
2. What train length and clearance envelope apply to that formation? measurement

Boarding and circulation fit

Record door positions, inter-car passage arrangements and interior constraints needed to assess the intended service.

1. Which door layout and inter-car passage arrangement are fitted to this MP 89 configuration? definition
2. What capacity and accessibility provisions are documented, and under what loading assumptions? measurement
3. Does this configuration align with the proposed platforms and any platform doors? boundary

Running-gear compatibility

Identify the functions and limits of the fitted tyres, wheels and guidance equipment from MP 89 technical documentation.

1. Which components provide load support, lateral guidance and passage through switches in the documented MP 89 arrangement? definition
2. Which minimum curve radius, gradient and running-surface limits apply to this configuration? measurement

Verified motion envelope

Require applicable supply, traction and braking data before assessing movement capability.

1. What supply voltage range, current-collection arrangement and traction equipment are specified for this MP 89 baseline? measurement
2. What speed and braking limits apply under the stated load and adhesion conditions? measurement
3. Which documented restrictions apply when traction or a braking subsystem is unavailable? action

Line-specific control fit

Treat train-control compatibility as evidence tied to a configuration and route. Alstom's 2018 line 6 announcement identifies I-CBTC and the RATP OCTYS framework but does not establish installation status for an individual train.

1. Which onboard control and radio systems are actually installed, and what acceptance evidence covers their versions? provenance
2. Which route-side system and operating regime are accepted with this MP 89 configuration? boundary

Mode-dependent movement permission

Record the documented relationship between driving mode, door proving, movement authority and intervention responsibility.

1. Which normal, depot, recovery and degraded modes are authorised for this CC or CA configuration? definition
2. Which door, braking and train-control conditions must be proved before movement in each mode? action
3. Which responsibilities belong to onboard staff and which belong to central control? boundary

Configuration-specific maintenance

Use applicable limits for tyres, guidance equipment, brakes, doors and inter-car passages; do not invent intervals or recurring failure claims.

1. Which maintenance instructions and revisions apply to the fitted MP 89 components? provenance
2. What measured wear, pressure or functional-test results determine replacement or restriction under those instructions? measurement
3. Which documented defects require withdrawal, restricted movement or further inspection? action

Accepted modified configuration

Link formation, control-system and refurbishment changes to applicable acceptance records and unresolved limitations.

1. Which completed modifications distinguish this MP 89 configuration from its earlier baseline? provenance
2. Which standards, operator reference documents and approval requirements apply, with issuing bodies and revisions? provenance
3. What inspection, test and acceptance evidence is still required before the intended service or transfer? action
