I may very well be Bachmann. I've only ever had one WBB item (about 8 years ago) but would be excited to see this in O Scale and would buy an Amtrak one in a heartbeat. Now if they did the would do an optional nose cone for the SCB-40 and put one in Brightline colors, I would buy one in half a heartbeat.
That being said, as Jonathan said, maybe 3rd Rail would do it. I'll jump on that one too.
