Monorail is out of service

Not to mention it takes close to 1100 amps to even get a train rolling. Batteries are not an option.

Many Subway trains have batteries that can deliver in excess of 10,000 amperes to get them past sections of track which have been momentarily been de-energized, So batteries ARE an option.

The batteries in my F250 superduty can deliver 1,700 amps for cranking and running the glowplugs on the diesel engine. Yes it's 12 volts but in many cases where very high amperage is required for an application it's easier to generate with a battery bank than a power supply.

When we speak of neglected maintenance with the monorails, the beam is part of that (among other things). Even new trains won't work on tracks which have been neglected to the point of failure.
Really, the beams have not been neglected to the point of failure. They're in decent shape - need a good clean and some patching, but they're structurally fine and built to last. The power system is showing its age, but has also been upgraded over the years. Some components still need replacement, and will be worked on.

That's what the tractors are for, though.

The idea is to avoid the delays of getting the tractor out. I understand there is a tractor now at the spur line to reduce response time, but a battery backup can get all trains safely back to a station much quicker.

You'd have to reengineer the trains. Kawasaki just started manufacturing batteries that can handle the needs of monorails and automated trains that lose power as of 2014.

This is the argument I am trying to make. To seamlessly have the trains switch over to battery backup when the beam loses power is not something I think we can reasonably expect. But, to have a configuration in which the train can creep to a station is not that far fetched. Hit a switch, power a few motors, and creep 10mph to the nearest station.

That's exactly what happens on a subway car when it loses third rail power, A/C shuts down and car 'creeps' along till it gets to station or powered section of track.

Big lead acid batteries have been used for decades for this purpose, The Kawasaki batteries are much smaller and lighter.

When I talk about the 'Monorail' I'm talking about the entire SYSTEM including the beam, Example airliners are useless without long runways.

Without giving this a lot of thought, and being uneducated on the electronics of the monorail, the claim that it takes 1100 amps to get the train moving is under normal operating procedures I would assume. Therefore, reducing the amount luxuries, such as AC, audio, and not providing power to each drive motors, I still think a limp mode is possible. The train may not reach 45mph, may start out much slower, and not be in a nice AC environment, but it would beat being stranded.
That is specifically just to move the train, not taking into account any on board electrics other than motors.

True, but for steel wheeled carriages, which support a huge amount of weight with a different center of gravity. I suspect there's a difference in having on-board batteries between normal light rail and monorails, which were designed to run with a continuous busbar vs. trains that have batteries on board. I don't know. There's a reason somewhere why the Kawasaki product is the first of its kind specifically for monorails. Will ask people who would be better informed. :)

I would not rule that out for the next generation of trains.

Oh absolutely - the current monorails would need to be redesigned to fit any type of battery system because it would add weight and change the center of gravity, I was simply speaking to those who said it would be impossible to fit a monorail train with batteries.

You might be able to place a short 'car' in the center to contain the battery system which would have the advantage of removing the batteries from the passenger cars.

The key to the monorail is that it's a SYSTEM and ALL the parts need to be designed to work together, But Disney definitely needs to spend more on SYSTEM maintenance and that includes everything from the monorail's connection to the electric grid to the doors and carpets.

And a story about how they are trying to create a driverless monorail system that runs on the RFID technology.
It seems like whatever they were testing might have gone awry... take it all for what its worth, absolutely nothing, but there it is, my first hand account of time time that the monorail went down and everyone's heads exploded.

The Thales SelTrac system being installed is basically driverless trains over Wi-Fi, so they aren't that far off.

Didnt the beans beams had maintenance last year (because cabling was needed for the MyMagic and Infrastructure upgrades) ?
