Finished! This locomotive has been a longtime dream of mine, as mentioned in the page dedicated to the work-in-progress. Seeing it complete means a lot to me, considering the times and circumstances under which it was designed.
I've also decided that my LEGO railway will be referred to as the Pacifica Railways. The 2620-class 2-6-2 Prairies were designed as a general purpose locomotive; but due to their generally smaller size, they maintained the schedules on secondary passenger trains as well as on some branch line freights.
When the large passenger trains of the Pacifica were combined under the three 'Riviera' trains, the 2620-class finally broke into express passenger service. Although needing a small amount of modernization, they managed the schedules of all three smaller 'Rivieras' as well as the somewhat later Combined Riviera.
Very little needed to be done to complete the build; fleshing out the firebox and ashpan were the most significant changes to the overall design. The cab was also altered to remain proportional. The tender remains unaltered, but a few details still remain to be added to the front panel which hides the Power Functions receiver. This remains removable in case channels need to be changed. I have not been able to find a good illustration of the front of an oil tender as of yet.
Possibly my favorite detail on the locomotive is the complete backhead in the cab. Crammed with valves, levers, and other details in the manner real locomotives are, this cab is an experimental exercise in detailing. The 2620-class is a relatively unsophisticated locomotive; and with great practice and concentration, could conceivably be operated by one crewperson.
I love it, other than the tender. It looks too big in comparison to the actual locomotive. I think something between 14 and 18 studs long would look better. However, this is still a wonderful looking locomotive.
