Thanks Mike , I am not actually using the pic as a proportional reference but more of a contruction reference . I have a 2d blue print of the side and rear of the train to get the length and width but I have to use what images I could find of the same model of the train but not exact to the blueprint I have so I could figure out what the componnents were and how they relate to the 2d image.
It is proving to be a challenge with out a front or top view but it matches well to the two 2d images I have.
I worked on it a little more but not much to post yet so I will wait a little while before posting an update.
I do plan to animate it eventually so I am trying to model it as best I can with that in mind.
