Comments on: Train Picks Up and Drops Passengers Without Stopping

Passengers wouldn’t be mangled, the car is connected to the train until the door is closed, then it is detached from the train. The risk occurs if the monorail track runs out before the door is closed. Lets assume that the monorail runs the entire length of the track.

The issue would be accelerating the transfer car with passengers in it. The acceleration required may be too much for passengers to handle. Deceleration wouldn’t be an issue as time is not an issue.

The biggest issue is cost, stopping the train would be less expensive who cares if passengers have to wait. Except the passengers

actually, since trains can switch tracks at even high speeds, couldn’t they have it like this:

1) approaching the station, the train switches onto a track that is essentially a circle going around the station so it just keeps going round and round

2) The transfer cars are on a similar circular track on the inside of the circle. They pick up speed as the train approaches and will match up with the train at the same speed.

3) As the passengers embark/disembark, the train and cars are going around at the station in circle. This ensures that, given a problem or some sort of delay, you wouldn’t have that ticking clock problem.

The problem here is that it partially defeats the point of the fast passenger transfer, but it increases safety and still eliminates the stopping and start up times.

OR………

a jet car that flies to meet the top of the train and lands on it. people transfer, then the car takes off from the top of the train. Any good artists want to take a crack at some concept art?

No mangling? Where’s the fun in that?

Happy Halloween!

Great idea. And you couldn’t mangle passengers if the doors to the transfer car shut well before it started slowing down.

It would work as long as getting on and off the train was automated.
Have the passengers stand in elevator-like boxes.
As soon as the transfer car matches speed with the train and docks,
the passenger boxes are exchanged and the car decouples and brakes.
On the train, as soon as the newly boarded passengers leave the transfer
box it is moved to the disembarking position for the next terminal.

PS: Were the car fail to decouple, the entire train would have to stop.
….or be destroyed. Whatever.

In order for this to work, the side cars would have to function like the aforementioned slip coach. If the cars stayed with the train until the next stop, it would give people plenty of time to embark and disembark the train. The trick is designing a safe way to pick up and drop off the cars.

This is essentially how many of the rides at Disney World work, although they use a continuous moving walkway running at the same speed as the passenger cars rather than an enclosed car. I don’t think it would work very well at higher speeds, though.

This was used in the UK between 1858 and 1960, for dropping passengers off at a station. Instead of a separate car, the last coach in a train was uncoupled before a wayside station. It used it’s own brake, and some clever point switching by the signalman…!

I love this idea. Would speed up travel time as most time is spent waiting for people to get on and off. You would have 2 of them one ready to go and one just arriving letting people off.

To stop people from being trapped in doors you only have the doors open once it connected to the train or platform and closed & locked prior to arrival or departure.

What could possibly go wrong?

This was actually proposed again recently, but with the “mono-rail” on top of the train instead of alongside:

The same comments about mangling passengers still apply.

Sweet Jumpin’ Jeebus. Do inventors actually try to find ways to mangle people?

Yeah. This was a good idea lol.

Have you seen how pokey people are leaving an airplane? What happens if someone is only halfway through the door when the monorail needs to start braking? Yikes.
