Looks good Andrew! Do the headlights work going both ways on the orignal model?

No they don't.
On a side note, I came across some strange glitches on that run. The first one happened when I was pulling out of Trapp Yard. For some reason the centerbeams got stuck on the switch and I couldn't move forwards. I ended up having to back up to the other end of the yard and use another track to get out of the yard. Then I got stuck again when I was heading upto the bridge, I had to use throttle 8 with sanders going to get through that one at 1.2 mph. Everything was fine from there until the return trip. I was coming up the Hyland hill when the loaded beams I picked up got stuck on a strait section of track. 1200hp should be plenty to pull 8 loaded beams up the grade so I don't think it was a lack of power. I quit the activity after that. I'm not sure what the deal is on this one. It might be the GMD1's or the centerbeams, or it could be a track problem. I guess thats a question for the lmrr guys.

Want me to do a few test runs with them for you Andew? Could run them up some other heavy grades and see what happens.

Not sure what really causes that problem but my guess is the combinations of tight curves that cause some locos/cars to do the 'happy dance' as they come around the curve.
This use to happen on the CN loop at Thornton Yard when it was a combination of 150r, 120r, 90r curves. The locos would just choke on loop and then suddenly take off. After replacing the loop with a piece of dynamic track of consistant radii all the way around, I could coast 4 Dash-9s around the loop with ease.
Trapp Yard - uses 6dB switches on the leads which use a 101r curve, not much I can do here.
Fraser Bridge - currently uses a combination of curves on the approaches, this was laid before I had Mtracks and will be fixed.
Hyland Hill - if memory serves this has the steepest grade on the whole route, if not the second steepest after the assault on Mt Lehman.

Ok that would explain the first two. I'll just have to start trains with longer cars on the sidings with the gentler switches in Trapp yard. From what I have heard, Scott Hill, Hyland Hill and Mt Lehman are all 2.7% grades. I got my train of 10 empties up Scott Hill with no problem. The return trip had 8 loaded centerbeams so I wouldn't think that would have been a problem. I was doing a steady 13-14 mph up the Hyland hill until I reached a certain point and my speed dropped to 0 in two seconds flat. I tried spliting the train in half but I couldn't even get that forward a few inches before I started going backwards again. I'll try again using more power to see if it is a power shortage problem or not. I don't think it is a curve thing because that stretch where I stopped has a very gentle curve or is strait. Anyways I'll experiment with it and let you know what happens. On a side note, I had the happy dance problem when I took some auto racks over to Annacis Island which is a problem considering a lot of the traffic that goes over that bridge is autoracks.

Well that information is good to know when the time comes to make activities for the route. Like Andrew said just start things on gentler sidings.

Ok I tried the run again with two GMD1's for power and I didn't have any problems at all on Hyland hill so I guess it was just a horsepower problem. I guess the spot where I stalled was a place where the grade gets steeper. Its amazing how it takes 2400hp to pull 8 loaded beams up a 2.7% grade, its no wonder why SRY puts so many locomotives on its trains sometimes.
