Transrapid
Advantages of the Transrapid
The Transrapid was developed to overcome the technical limits of wheel-on-rail trains. Here is what that means in practice.
At a glance
What sets the Transrapid apart
Up to 500 km/hThe Transrapid is designed for 400 to 500 km/h. Chinese variants are aiming for 600 km/h.
40% less energyAt 350 km/h, a TR08 needs 40% less energy per seat than an ICE 3 (Deutsche Bahn's high-speed train), and 30% less at 300 km/h.
ReliableDedicated infrastructure and few wearing parts: in Shanghai, availability is 99.96%.
Flexible alignmentGradients of up to 10% instead of 3 to 4% for the ICE. That saves tunnels, and on an elevated guideway the line passes over roads, rivers and railway tracks.
Quick to full speedIt reaches 300 km/h in 4.3 km (98 s), while the ICE needs 17.9 km (324 s). That makes it worthwhile even with many intermediate stops.
Relieves other trafficAnyone who switches from car, ICE or aircraft frees up rail capacity for local and freight services.

Environment
Good for the climate, the landscape and your ears
Fully electricPropulsion and levitation are both electric. Depending on the energy mix, the Transrapid runs climate-neutral and can replace short-haul flights.
Long-lastingThe guideway lasts 80 to 100 years without major repairs. There are no wheels to wear out.
QuieterAt 300 km/h, the Transrapid is only half as loud as a TGV and has passed after three seconds.
Less land useOn an elevated guideway it does not cut up the landscape. Fields remain usable, wildlife can still cross, and level crossings are eliminated.
Economics
Same construction costs, significantly lower operating costs
Despite double the speed and a long service life, capital costs are roughly on par with the ICE. The advantage grows over the years of operation.
Investment on par€17 million per double-track kilometer for the Transrapid Hamburg–Berlin, €30.9 million for the ICE Nuremberg–Ingolstadt (Siemens, 2001).
About 70% lower maintenanceAcross the whole system, maintenance costs are just under 70% below those of the ICE.
Low energy costsThere is no rolling resistance, and with a comparable number of seats the vehicle weighs only about half as much as an ICE.
Less staffAutomated, low-maintenance operation requires fewer staff.
