In addition to the main crew, other members of the Trainz Narrowgaugers contributed their invaluable expertise as well.
This is the crew who built the original model of the DHR. It took over three years to create. The rails were laid from one end to the other and matched to a Digital Elevation Map of the entire route. In order for several persons to work on it at the same time, it was broken into segments. When each segment was completed, it was joined to a master map. This master map then had the last scenery details added.
