I told myself that I would do the late-style Portager after my early phase one, but with few photos to go by, I felt I was doing too much guesswork. I'll save that project for later once I figure out a better way to do it. While looking around for drawings for a replacement project, I found some information that would help me make a reasonably accurate 500 Series Shinkansen. Tenshodo, usually a brass company, had Bachmann tool them a plastic one, so an HO model of it already exists, but I think there is room for improvement. They are available in 5- or 6-car sets and can be found on eBay sometimes. However, the prototype was 16 cars long. Then, the 500 series was shortened to 8 cars after newer models replaced them on the top schedules. 16-car W sets ran on the top speed Nozomi services from 1997 to 2010, after which they were rebuilt into the 8-car V sets and relegated to slower Hikari and Kodama schedules. There are no expansion packs available for the Tenshodo model, so it is impossible to build an accurate V set, let alone the full 16-car W set. This is where I come in. Right now I am making a 'master' file that I can modify into each of the different car types. I copied the dimensions from the Kato Kinematic Coupler, allowing for a pretty much drop-in fit. Close coupling and wide curves make those high-speed train models look super sleek, so I know it is a feature I want to include. This model will be super involved. There wasn't really anything to the Portager, just two end frames and the spine, but this is different. I have been doing a lot of photo overlays to make sure I get the underbody panels and windows lined up on the model, and with multiple car types required, I am just repeating the same steps with slight changes in measurements. For the 8-car set, there are 6 different underbody types, while all 8 carbodies have some feature that makes them different from the rest.
