Blowdown fail: FIXED. My 2-10-10-2 #3008 Valley Flyer arrived last week. A stunning locomotive. Looking at it is like sitting in front of a fire, it's hard to look away!!! Two initial issues. The blowdown steam effect worked once, then nothing. Initially the Engine just stopped as if it hit a wall. Why it stopped, I don't know. Fortunately, that problem has not repeated itself. The blowdown is another story. The whistle steam smoke effect is amazing. Blowdown would not work. The dreaded 3-blinking cab light came on. A reset worked in eliminating the blinks, but the blowdown still didn't work. Called Lionel resigned that I would have to send it back. However, Kristen, the customer support person I spoke with told me that since the whistle steam worked, it's probably not an issue with the smoke units, so she suggested using a shot or two from canned air directly into the exhaust port on the side of the loco. That was verboten with the Big Boy, but I tried. After a few attempts, whatever was preventing the smoke from ejecting was dislodged (?) so it now works 110%, to quote John Glenn. Kudos to Kristen and Lionel Customer Support! I've been running the loco 3-4 times a day for the last 3 days and everything works great.
