Actually I've printed 2 of them. The first is predominately blue and needs its trucks and detailing and possibly painting. The second is mostly printed in BNSF orange and green and is a few weeks away from Assembly. I likely wont power either of them as I don't have arail road nor easy access to one. I've got to say I have enjoyed the projects so far.
Rafts were only needed for the cab roof and supports for the cab and motor housings.
