Overall I don't think so, when I converted the engine, I replaced the existing weight with a Dash-9 lead weight because of it's dimensions. It might have added a little weight, but I don't think much if it did.
For what it's worth, I just got the last 5 cars in from Ridgeroadstation so the traveling set of cars (that stay in boxes) is now a complete 60 car set. So at the next show we will get the redo and it will be a true 60 car consist, not 55.
Sorry again for the mixup. /DesktopModules/NTForums/themes/mls/emoticons/tongue2.gif
