MagLev train design

Design MagLev train for Propulsion force only for Roller-coaster ride. Assume the track as infinite as it is in loop. No need of making the train float in Air. Only 400 N - 600 N forward propulsion force is required with speeds up to 120 mph - 300 mph. The wheels of the vehicle will be resting on the floor/track, so airlifting of the vehicle is not required. If you need more info, let me know. When you submit bid, submit with final amount and no placeholder amount. Write MagLev at the beginning of the proposal, so I know you are not Bot and understood what is required. Without MagLev Keyword, you won't get response. You can use any simulation software you are comfortable in.
