See what I mean? With the last update I mentioned that things were changing again, and here are those changes now in the form of a full revamp!
This is the result of about 20 hours of failed experimentation followed by 10 hours of building & fine-tuning the one actually feasible concept. This train is now entirely 4 studs wide at last, while the first version had a wire ribbon that traveled along the outside and both v1 & v2 had vanity tiles covering some unsightly bits. The motive & battery cars look rather rough around the edges and unnecessarily asymmetrical front to back, but believe me, there is rhyme & reason to every piece on this thing. I even built the new rearmost car with lightness in mind, carefully substituting parts repeatedly to minimize the mass plastic used to create a desired shape or connection.
Is this the final version of this 4-wide train? I am certain it is not. However, I should be able to leave it alone for good while, as it no longer bothers me when I look at it.
Man, I need a break! This was tough!
