Kewl, I have my fuel tank cover drilled and ready to accept sound. I am taking a bunch of 6 axle Athearns down to the hobby shop to sell, that will generate funds to purchase a sound decoder for the unit. Once I get the new decoder, I can wire up the yellow double flash strobe on the roof. For now only the hole for the bulb is there. I almost have the engine ready for paint. Check out the pic in my "chop nose GP7" thread. Mike
