    Default NALW Jet-Train.....

    A GREAT change of pace.

    I just ran it from Barstow to Mojave on Cajon Pass and got it up to 143mph, although it's redlined at 135.

    It brought back some vivid memories for me.

    In the mid 70s I worked for Air Research Corp. at the DOT Test Track near Pueblo Colorado. I was an instrumentation technician and pilot for the LIMRV (Linear Induction Motor Research Vehicle) which used a turbine engine to power an alternator that provided current for a linear induction motor. The motor was a saddle of coils that fit over a vertical reaction rail...a motor that, in effect, had no moving parts. It worked much like your electric meter works except that the disk was a vertical aluminum fin that ran down the center of the track.

    For a time that vehicle held the world speed record for steel wheels on rails, about 230mph. We ran it manned for tests up to 190mph and remotely at test speeds above that.

    In the latter phases of the testing we installed two Hound Dog missle engines on the sides to increase acceleration to reach the higher speeds since we only had 7 miles of track. Once we attained the test speed we'd cut the Hound Dog engines back to flight idle and run with the LIM only.

    Thanks NALW....your rendition of the Bombardier Jet Train is close enough to the LIMRV to bring back some fond memories.

    Is that the Train that sits with all those historic Planes at Pueblo's Airport they have a jet powered train that sits there.

    Yep. It's the bullet shaped one with the two jet engines hanging on the side. The big one was a Grumman air cushion vehicle that was also a linear induction motor testbed. It ran in a concrete guideway. It was also an Air Research motor in the Grumman vehicle. I assisted in the installation of that one.

    There is still a dent in the nose of the LIMRV that was the result of a collision with an owl at 100+ mph. I wasn't operating it at the time, another operator was. It scared the bejeezus out of him.

    Noel we're glad you like it....

    Your reaction is all the pay we need....

    This was truly a labor of love to build this set....

    BTW, FWIW that is not a Redline at 135!
    That is the highest Signal Speed MAS for the NEC which is what we set that cab up for....
    You will see that red line change as signals change in front of you...

    I believe we are also set to redline at 30mph and 45mph with the proper approach signals set and it will redline at 0 for restricting...

    Default RE: NALW Jet-Train.....can't see engines...???

    It's great! I love racing it down the Florida High Speed Rail route..

    One problem though...in external view why CAN'T I see the locomotives? Like ghost trains. Did I goof up?

    Thanks!

    I like the way it sounds also I topped it out 162mph on MP3.1.

    I do have one complaint Chuck. The dynamic brake doesn't seem to work. I've tried it from the keyboard, my RailDriver, and the mouse. The combined handle stops at the center of travel and won't move anymore. I assume there is supposed to be a dynmaic brake by the looks of the amp meter and the fact that the combined handle throttle is 0% at the center of its travel.

    Noel it uses "Blended Brakes"!
    Which given the limitations of the MSTS1 Engine do not allow you to manually control the dynamics....

    How they are implemented in the Physics Engine is that you apply brakes and the computer decides how much of each type (DB and AB) to use.... mostly what you will see is some type of air applied and the ammeters twitching slightly as the computer steps in and out of dynamics.... Its obviously more complicated than that but that is the simple explanation.... They are working "as designed:!

    Hah! I hit 230 going downhill on Cajon Pass. Damn it was like being in an F-16.
