Hydraulic Systems - Train doors?

[duggie_1001]

Hi,

So as can be seen on my Previous thread I am trying to develop a new more efficient seating system for trains in peak hours.

I have developed a mechanical concept which could be driven by a hydraulic system. I however have a pretty minimal knowledge of hydraulics, especially on trains.

I am assuming train doors are run on hydraulics and was wondering if anyone could provide me with any information on where the hydraulic system is and how it runs? Could i run a potential new system off the same pumps?

Any general potential problems and reccommendations are appreciated.

Cheers

Ryan

I would have thought that if you designing a ridical new train and systems then you would have researched the subject prior to starting the project. Surely you must need to know in advance the current designs and systems in order to improve on them, not design something and then ask questions of existing designs.

On sliding door stock (such as the mark 3 multiple units and PEP-based MUs) the doors are pneumatic.

I think some with plug doors have mechanical drive from small motors?

You wouldn't need to know current designs off to a tee, you'd have a basic view of them and just make them better, innovation against the competition is making something better than they have.

Virgin Airlines and British Airways for example,
British Airways have comfy seats,
Virgin Airlines bring in better seats they don't worry about how the seat works or whats inside the seat. they just know their seat is better

Correct. The Desiro doors are mechanical, they're extremely slow and as a consequence the new gen Desiro will have new doors with new mechanics that close quicker.

The Electrostar doors are mechanic, which is strange, most of the technology on the Bombardier products is hugely outdated! The doors open and close very quickly, and are far superior in that respect to the Desiros.

390s and Voyagers/Meridians have mechanical systems as well. The mechanism for Voyagers is clearly visible above the doors.

Certainly Desiro doors are mechanical, and I think that is the standard for plug-door types these days.

Not sure of any train that uses hydraulics for its doors?

Well Delt1c Thanks for that constructive response!

Seeing as normally designing a new train takes a team of 100 people 2-3 years to complete i hope you can forgive me for not knowing how every single component works! I am designing a new seating system and trying to incorporate it with existing components not inventing a new super train.

I see, so doors are more often than not mechanical. So they just run on geared drives?

Possibly 158/159s and 442s?

Glad to be of assistance
If it takes 100 people 2 -3 years, reckon you should have employment for a considerable number of years

You did see what all this is in aid of didn't you? Or did you not read the other thread linked above?

As any power door uses either air or hydraulic oil which need compressing by a pump, driven by an electric motor. I say cut out the middle man and power you doors by brushless electric motors

I believe some of the older tube trains have/had hydralic doors.

 

[duggie_1001]

im looking a driving a mechanism i have desinged for moving seats. it will probably use a rack and pinion drive so i felt hydraulic was the most viable

Be aware of the start up and stopping speed and the speed of movement needed to cause nausea, including the fact that the 'horizon' out the window is also moving at speed! Nausea can be induced at very low speeds.

165s have the best train doors. They hiss as they're about to close then slam into eachother

Sounds like my local on a saturday night, everyone hisses when about to close , then everyone slams into each other when they stagger out, reckon it should be renamed the Thames Turbo Inn:neutral:
