Both! I have been a bit hesitant to get the APT out - I need to set up a test track as my layout will cause an APT rhino-ectomy. The Jinty is planned for a sound chip and possibly working lights - I just need to order the chip as the file isn't available as a download in the ESU website.
I believe you can reblow select chips but not edit them. The ESU website has all the select sounds as down loads but they were mostly US types when I last looked. Unfortunately for the the V4 there are very few UK sounds available so even though I have a programmer I can't easily put sound in my fleet without ordering chips from the UK (although at the current $US exchange rate maybe I should!)
Post #166 has a U tube video with the crew and passengers / technicians in it! Drivers seem to be in standard dark blue with peaked caps, engineers seem to be "smart casual" however the beards and flares my be challenging...
