Viewliner II Delivery/Production

Any way that could be added for the diners and sleepers? Id think it would be a good idea in case a chef burns something and it stinks up the diner or bathroom ventilation on the sleepers. Just my two cents.

I took it as a reference to Baggage cars only.

There's a wheel slip system?

If you look at the video from Kissimmee you can see a thin, silver conduit running across the top of the truck and down to the wheel bearing. This is a proximity sensor that "watches" the bearing end cap and is wired to an electronic decelostat.

Think Mr.Okeefe tried to be anal by pointing out that slip only happens on powered axles, yet the WABCO decellostats are sold sold as a slip/slide system.

These do not have wabco decelostats they have the MGS system made by Knorr like the amfleets. Most of the old baggage cars that were passenger cars have the E-5 decelostats from wabco. Any of the heritage diners with disc brakes have decelostats.

the WABCO E-5 was also used on the Budd SPV's , needles to say they were F**kted when they took drive shafts out from outer axles.

I think this photo illustrates how well the Phase IV on the Viewliners matches that on the Amfleets. I just don't get the logic behind the mixed color scheme thing that Amtrak is going for.

Not in the least. I'm not familiar at all with these types of passive (?) systems on non-powered axles. More than happy to learn about it though.

The slip slide system in its basic form is a comparator card which counts gear teeth with a proximity sensor, when any of the axles don't match the speed of others either brakes are released on that truck. (or power is reduced if powered axle)
It prevents car from getting flat spots, bad thing still is when extremely slick like leaf season of all axles lock up it will no longer see the problem so entire car will slide.
same with powered axles , if all wheels spin, the comparator card can no longer see difference unless equipped with some kind of ground speed device like some engines have.
its a simple kind of ABS system.

Are these self powered or would they typically have some kind of low voltage setup from the car's power?

system is powered of car's battery system (64 volt) which in turn is charged and maintained by HEP.

In the field we use "decelostat" as a generic term regardless of make. Not technically correct but we know what we're talking about. Maybe when some newer stuff filters down to us that will change.

Yea the MGS system is a deceostat, i know that what i meant to say is it wasnt a wabco product.

The silver box in the center of the skirt is the car's HVAC unit: http://www.rrpicturearchives.net/showPi ... id=3965228

64 volt? That seems like it's from the bygone era of the 32-volt farm windchargers. http://www.windcharger.org/Wind_Charger ... _Fame.html" onclick="window.open(this.href);return false; There's not a farmhouse left wired for 32-volt power, yet here in the 21st century we're using 64-volt systems in brand-new railroad rolling stock.
