    Actually two hours is incorrect. TR said "average" speed. You then don't actually know what the actual speed was over what time period. So, if the question was phrased as constant speed then the answer would be two hours.

    130 + 110 = 240mph

    480/240=2hrs

    But given that there's not a train in existence that can instantly accelerate to over 100mph, there would still be quite a bit of error in the calculation.

    The train will not fly.

    If it accelerated to 150 and stuck there for a few minutes then dropped down to 130 and was a tilting train so it didn't have to decelerate for corners... then it's possible.

    A train that "leaves the station" is assumed to have been at rest, otherwise it would have been "passing by the station".

    You didn't know that Daimler Chrysler was making trainzorz now did you? DC Trains are belong to us. With a Stage 2 kit and an upgraded cow pusher (you know... Front Mount) they are having negative 0-60 times. IT's a BAMF, because the BOV sounds like a train whistle. (Trying to stay on topic. )

    I was watching a video on youtube today that said the kid had the SPT intake and exhaust, but the car also sounded like it had a BOV. Is this noise associated with the intake, or does he have a BOV that he didnt list? thanks for the help...here is the video clip.
