'6060' series 1UF Mountain and
After several requests to develop the 6060 series U1f Mountain type 4‐8‐2 locomotive in 1.6 inch scale the search for original drawings and any information and photos were gathered and the serious research began. The deveolment on computer began to take place about 3 years ago. The boiler was designed and went to the boilers branch for their stamp of approval. Next our boiler maker, who is cerified in all jurisdictions of USA and Canada, went to work. All boilers are registered with the National Boiler Bureau in the US and Canada. They are stamped with the NB and S stamp for the US and the CRN # for Canada. All boilers are inspected by the boilers branch during manufacturing stages and are annealed and stress relieved as well as x-rayed before final certification is issued. All boilers are designed and approved for 175 psi operating pressure.
This is how this locomotive is built on computer to check how parts fit. A lot of interferences are discovered here in a 3d drawing. Click here for full-sized image.
