APT tilts thru curves in Real-Build ABS form —James Mathis
My attempt to model the British Rail Advanced Passenger Train set is progressing. The "real-build" ABS consist is: 1. cab unit (driver trailer second) 2. passenger car (trailer second) 3. passenger car (trailer brake first) 4. motor unit (non (...) (23 years ago, 25-Jun-01, to lugnet.trains) !

	(...) <snip> (...) WOW! That is the sweetest looking passenger train I've laid eyes on since the Metroliner. And I'd even hazard to say that it tops the Metroliner. Words can't express how impressed I am with it. You've done an awesome job on that (...) (23 years ago, 25-Jun-01, to lugnet.trains)

		Re: APT tilts thru curves in Real-Build ABS form —James Mathis
		(...) I'm actually very ignorant as to how the real APT tilts. What little I do know makes me think that the pendular axis is very low; maybe just above the bogie near the floor? I think the APT used a very active forced-tilt with some kind of (...) (23 years ago, 25-Jun-01, to lugnet.trains)

				Re: APT tilts thru curves in Real-Build ABS form —James Mathis
				(...) You are so correct. I have thought of how to achieve this pendular effect ever since Eric Brok showcased a working solution with modified Metroliner. So, that's been a few years! Simple: Well, even sometimes the realized solution is not (...) (23 years ago, 23-Jul-01, to lugnet.trains)

	Re: APT tilts thru curves in Real-Build ABS form —Sam Hastings
	Cool! I love your train and the detail - I live in England and it immediately struck me as a british style train. Any plans to build instructions? I want to know how to make the 'tilted' red stripe (near the front) - or did you not have it tilted? (...) (23 years ago, 26-Jun-01, to lugnet.trains)

			(...) Thanks for the building tip. Gotta just love your building ingenuity. These tips definitely save me a lot of time trying to figure out how to incorporate these techniques. Man, that's one long train. Sure hope you don't have any inclines on (...) (23 years ago, 28-Jun-01, to lugnet.trains)

				Re: APT yellow-red 73degree slope stripe SNOT construction (was Re: APT tilts thru curves in Real-Build) —James Mathis
				(...) I certainly can't take credit for this; I'm sure other folks have done it before me! Just a matter of timing and awareness as to where the idea shows up. It's a good construction technique; one that I had to use because I don't own any inverse (...) (23 years ago, 28-Jun-01, to lugnet.trains)

	Re: APT tilts thru curves in Real-Build ABS form —Christopher Masi
	(...) You are a genius. Here I am spending my weekend building Mini's[1] while you are building an APT. It looks great, and the pendular mechanism is simply the result of the centripetal force, right? Very nicely done. Chris 1. I mention the Mini (...) (23 years ago, 26-Jun-01, to lugnet.trains)

		Re: APT tilts thru curves in Real-Build ABS form —James Mathis
		(...) The pendular mechanism has a lever-arm-wedge that pushes "out" and "up" on the undercarriage. The tilt could be the result of the centripetal force through a curve, but weight of the car and the "zero" gap above the bogie plate between the (...) (23 years ago, 26-Jun-01, to lugnet.trains)

	(...) Awesome, I'd even allow this to run on my layout! (and I'm not a pasenger train type of guy either) Quite a neat job on that one, James! -Harvey (23 years ago, 27-Jun-01, to lugnet.trains)
