Quick answers
Which local authority or corridor rules matter for this type?
Start with the local lens: type approval, operator licences and the hubs named on this page — not a single global checklist.
Is this a buying guide?
No. Tool-Lifes /vehicles is an educational atlas. It explains history, systems and culture without affiliate rankings.
Are the scores official?
No. The six scores are relative editorial 0–100 marks across the 48 types on this site.
Where do the photos come from?
Lead images resolve from Wikimedia Commons via Wikipedia titles on the English masters, with licences recorded on the credits page.
Why metric units?
Metric is the default. Regional notes (US customary, local brand culture) appear in culture and market chapters.
How is this different from a wiki article?
Each type gets seven fixed-depth chapters, comparable scores and cross-type labs — structured for browsing, not a single freeform page.
Operating a Maglev is a closed loop: sense, decide, actuate, and stay inside certified envelopes.
Principles and steps here are physics-first; brand procedures differ, but the envelopes are shared.
Principles
Electromagnetic gap stiffness
Attractive EMS or repulsive EDS systems have different stability margins.
Linear motor thrust ripple
Slot harmonics cause vibration unless skewed or controlled.
No wheel adhesion limit
Acceleration set by motor thermal limits, not creep—until landing speed.
Edgy current drag
EDS systems have inherent drag even at cruise affecting efficiency.
Guideway capital intensity
Performance tied to slab precision more than vehicle mass alone.

Operating steps
02 Sync to LSM
Lock motor phase to train position sensors along guideway.
03 Cruise control
Maintain gap and power factor; monitor cryo or inverter temps.
04 Regenerative slowdown
LSM braking returns energy where substation accepts it.
05 Landing transition
Reduce speed to wheel-support threshold before station.
06 Depot inspect
Measure gap sensors, guideway wear plates, and cryostat levels.
Hard limits
Levitation speed floor
Below threshold, train must run on auxiliary wheels.
Guideway maintenance tolerance
Micron-level slab specs cap operational speed after settlement.
Emergency egress
Elevated guideway evacuation plans define max train spacing.
