There will be an APT-P DLC!!!

[gptech]

happily the industry moved forward

the secondman might not have been so happy if it meant he was redundant......

Could it ever run again???

Pragmatism says not, but the prototype HST has been revived and extinct steam classes reincarnated.
Of course, it's money and will power that makes the difference - just look at what happens in the world of rare warbirds...

But, from an engineering perspective, how dead is a dead APT???

I would say as dead as the DoDo

There are so many items on the APT which were unique to that train - the brakes were Hydrokinetic, using liquids to slow the train down.
Tilting system was totally advanced - more than the later Pendolino & Voyagers.

Although it would be nice to see it running again I don't think it would happen.

Much more on topic. An in-depth look at the APT-P, note the two drivers in the cab. It sounds (description of features etc) and looks fabulous.

As an aside, regarding the trackside transponders for speed, depending how these work and if they're scenario specific, if we understand how they work might we be able to use them as a way of fudging limits for rolling stock below normal linespeed for use in scenarios I wonder??

Deffo my favourite shot, cracking detail in there.

Whoa. Impressive!

The attachment APT_0009.jpg is no longer available

Whoa. Impressive!

It does look realistic

There is a fund raising effort to get the powercar from Coventry to Crewe as they only have one, I think they have raised enough to do it now

I suspect a paint job will be next !

Obviously there was a few problems with the APT technically, with it possibly being put into service too quickly.
The thing for me which I can't quite grasp is there was loads of talk back then about passenger sickness, so what doesn't the 390's do the the APT did?

The appeal has reached its target but Brian is more than happy to receive anything on top as that will go towards preparing it for display. He has some great plans for it. Details are on the Facebook page:

When the APT came out the larger windows made the tilt more noticeable and the talk of people being sick put that thought in to peoples minds

Some people today still feel sick travelling on Pendolinos - especially if you go backwards

The tilt on the APT was so smooth you didn't realise you were tilting until you looked out of the window---that confused many people's minds, hence the nausea. The Pendo's (and all other subsequent tilting systems) introduced a barely susceptible 'sense of movement' before the curves so that the brain could come to terms with the fact that the axis had shifted.

Tilting trains are meant to help reduce the effects of centrifugal force on the human body, but they can still cause nausea, a problem that was widely seen on early "active" tilting trains that exactly balanced the outward force. The effect could be felt under maximum speed and tilt, when the combination of tilting outside view and lack of corresponding sideways force can be disconcerting to passengers, like that of a "thrill ride". Researchers have found that if the tilting motion is reduced to compensate for 80% or less of lateral apparent force, then passengers feel more secure. Also, motion sickness on tilting trains can be essentially eliminated by adjusting the timing of when the cars tilt as they enter and leave the curves. Systems typically tilt the cars based on a sensor at the front of the train, and the slight delay in reacting to this information leads to a short period of sideways force while the cars react. It was found that when the cars tilt just at the beginning of the curves instead of while they are making the turns, there was no motion sickness. To provide information about the upcoming curves before the front of the train reaches them, a GPS system is used.[4]

According to one documentary I've seen, quite a bit of the sickness came from the presspack and VIPs. Many of whom were sloshed before they boarded the infamous official launch train.

What made the press pack feel sick was excessive amounts of free BR alcohol. It's done that to me few times !

The APT tilt system compensated for 100% of the curvature, where`s the class 390`s and other tilting trains only compensate for around 85-90% of the curve, because of the full compensation that why some passengers felt travel sickness, and in the Pendolino`s you still feel a small amount of sideways force while taking the curves.

Which it basically what it says in Gary's post above

Comparing the pictures between the APT for TS and the real APT, I notice the oval buffers under the nose are horizontal in one picture and vertical in the other

Did they swivel ?
