Many maglev have lift-to-drag ratio that exceed that of aircraft.
But jet transport aircraft take advantage of low air density at high altitudes to reduce drag during cruise.
Airlines cannot come close to the reliability or performance of maglev trains in all weather conditions.
Has significant safety margin as they are designed not to crash into other.
The initial investment is similar to other high speed rail roads. (Maglift is $20-$40 million per mile and I-279 in Pittsburg cost $37 million per mile 17 years ago.)
Operating expenses are half of that of other railroads.
A train is composed of sections that each contain 100 seats, and a train can have between 2 and 10 sections.
The linear generators produce electricity for the cabin of the train.
TESTING TRACKS
120 m test track of General Atomics at San Diego , USA.
Tranrapid , a German maglev company has test track at Emsland ,
Germany of length 31.5km.
JR-Maglev , Japan has a test track that can reach a speed of
581km/hr.
IMPORTANT OPERATIONAL SYSTEMS
Linimo , Japan – commercially automated urban maglev system commenced on March 2005.
Shangai maglev train , China – EMS high speed system started operation on April 2004.
HML 03 – The first EMS maglev opened to public at
Daejeon South Korea in 1993.
UNDER CONSTRUCTION
AMT Test Track – Powder Springs, Georgia
Applied levitation test track – California.
Beiging S1 line.
PROPOSED PLANS
Penang-Kuala Lampur-Singapore line -Malaysia
Melbourne Maglev Proposal
Mumbai – Delhi
Kochi metro
They consume less energy.
Require no engine.
Move faster than normal trains because they are not affected by ground friction; their rights-of-way, meanwhile, cost about the same to build.
Incompatible with existing rail lines, unlike traditional highspeed rail.
Initial cost is very high.
