    Using Monopods for city travel utilizing linear induction motors

    That was never the plan. Stations will be under a KM, and possibly as close as under 200 m. I explained some aspects of it in post 75 for a linear city. I may add more details when I find the time. I did work out rough schematics. But the essential idea is you have large radius, fast and high...

    Using Monopods for city travel utilizing linear induction motors

    I see no reason why they would be limited. That's the entire point of point to point transport. You can experiment with different network layouts on a paper, test various topologies of high speed lanes and interconnecting lanes and try it out for yourself. I discussed the 2 different switching...

    Using Monopods for city travel utilizing linear induction motors

    It's more useful to see Shanghai Maglev is as a test track with a real world use case. It will take time for me source all this information, but if I recall the research I did correctly maglev is more energy efficient and lower maintenance than high speed rail at comparable speeds. One aspect...

    Using Monopods for city travel utilizing linear induction motors

    I assume you understood I meant attaching creating a double pod with a floor space of ~1m*2m. (width * length) But that's a tricky aspect. Children alone could justify a very different design.

    Using Monopods for city travel utilizing linear induction motors

    I have considered that, especially in the context of small children. It should be possible to attach 2 pods linearly to make a double pod ( in general N pods). But you need to pay close attention to tolerances in actual design. You need some kind of flex at the junction between pods for turns...

    Using Monopods for city travel utilizing linear induction motors

    To the people following this discussion I wanted to add few points unique to Maglev technology and not monopods. Which may be explored as the technology becomes more mature. For this post in specific I will assume typical 100-500 people per coach and typical train coach dimensions(~ 25m...

    Using Monopods for city travel utilizing linear induction motors

    I am not sure how you arrived at that conclusion, based on what I am saying. Safety issues I very much understand, I did rework the design adding a safe breaking distance, that's a small step. However for throughput, comfort and easy expansion, this is a far superior concept. In the cross...

    Using Monopods for city travel utilizing linear induction motors

    I believe those numbers are arrived at from terminal velocity not breaking force. A 6 m (cross section) diameter parachute applies a breaking force of ~6.4 g at 60m/s assuming drag coefficient of .5 for a 500 kg payload. And 1/4th of that value at 30 m/s. Even if it works well, just a random...

    Using Monopods for city travel utilizing linear induction motors

    You would attach it to the pod itself. And it would be triggered electronically by g sensors(or other automatic trigger mechanisms). The job of the parachute is to apply an emergency breaking acceleration, if the contact with rails is ever broken. Parachutes for payloads of 500 Kg's are...

    Using Monopods for city travel utilizing linear induction motors

    Couple of general points about a realistic city like Mumbai. 1) Mumbai is a linear city in the dense areas.(map enclosed). Local trains operate at a max speed of ~80 KM per hour. Curvature of tracks should be more than 3.6 KM to operate the pods at 100K per hour at 60m/s. ( I don't think...

    Using Monopods for city travel utilizing linear induction motors

    Honestly electric scooters are pretty good. They have an extremely low foot print per person. The drawbacks are you can't sit. They can't travel at 60m/s. They have a very low range. They are constantly at risk of colliding with something or someone. Add dedicated set of interconnected...

    Using Monopods for city travel utilizing linear induction motors

    There was a lot of time spent evaluating this idea before and during this thread. It has developed significatly during the course of this thread, because of the questions, and pointers(ex the squirrel comment), for that I am thankful. Mumbai metro pretty much runs at max capacity during rush...

    Using Monopods for city travel utilizing linear induction motors

    You can find a later review by the same author. He says "Second, guideways that must support conventional-sized rail cars weigh between about 2000 to 3000 Ib/ft. If the capacity of those cars is divided into many units of the smallest practical size with attention to...
