SBB Re 460 (Lok 2000) Locomotive

Hello,

Throughout the next several months, I'll take you behind the scenes as I build the SBB Re 460 from scratch -- maybe someone will find all of this interesting. The Re 460 will complete my IC 2000 scratch-built model, but I know lots of people will be interested in the Re 460 alone (so that's why it's in this separate message.)

Like my SBB IC 2000 model, I'll make this Re 460 model free to download once it's completed. I'll also make several variations of its livery.

Here's how this all got started. A few years ago while I researched a trip to Switzerland, I came across a really cool looking train with black and white stripes, and red door highlights -- I learned this train was called the IC 2000. Several companies sold IC 2000 toy trains, but these were *really* expensive and way out of my budget. With a Google search I found a paper model of the IC 2000 that someone built. It seemed OK at first glance, but the more I examined it the more I found *serious* accuracy flaws. I thought about correcting its mistakes, but in the end I decided I'd make my own from scratch. It took a while to put together in my spare time, but I finally completed it (without the Re 460) last November.

The Re 460 was up next, and it would complete the IC 2000 (which is a push-pull type train.) I gathered lots of Re 460 study images, my own images, and video screen captures to help me get the details right. Compared to my IC 2000 research, I found lots of Re 460 diagrams on the Web -- which was really helpful!

In January, I began to think about the shapes I would use to build my paper model. I could have based the design off my Bt carriage (from the IC 2000) model. However, the shorter inside area arrangement, needed pantograph area, and now more accurate Re 460 diagrams persuaded me to start almost from the beginning.

I first sized and aligned the diagrams to match the scale of my IC 2000 paper model. I do make my models with an internal structure so the paper sides can stay flat, not bow outwards with larger sized models, and provide support where needed. The most important thing though is that the structures support several bottels of glue--these weigh down and flatten the sides as they dry.

I next thought about where the internal structures should be placed.

Attachment 281507 Here, I mapped out the basic areas of the internal structures. I decided to place them under the pantograph areas, and in the middle.

I next began several sketches -- I actually sketched the pantograph first since it puzzled me the most, but I'll save that story for a future post.

Attachment 281508 I thought up several ways to do the internal structure shapes, which you see sketched here. One of my goals for the Re 460 model was to simplify the internal shapes, as compared to those in the IC 2000 model, and reduce the number of parts.

In my next update, I'll show photos of my first paper assembly. The various sketch ideas you see here were combined in different ways, so next time I'll reveal the internal structure I actually used.

Until then, cheers!
