i like the idea of digital control of the various leds... but i'm clearly in the minority. I don't think the HW would be expensive but to do what I want lionel would have to spend money to do it, and then marketing is not clear for getting new sales: "This new engine now has the option to individually dim or brighten all LEDs through command control -- flickering is even supported. Imagine the possibilities! Yes now you can have a dodgy number board on your layout all with the push of a button!"
