Brianel,
I have always regretted that we lost k line. They really did do 027 right instead of treating it as a "second fiddle" to the larger trains. I have thought for a long time that 027 is under appreciated. There are things that can be done with 027 that could not be done with the larger trains. An interesting 027 layout could be done in less space, for example. I have quite a few 027 trains in my collection and would not even consider selling them.
