Apparently nothing new announced from the traditional big hitters Atlas, Athearn, Intermountain, Trainworx, Wheels of Time, etc.
I had planned on going, being Long Beach is only a 4-5ish hour drive, or 45 minute flight from Vegas, this year. But between changing venues and a lot of manufacturers dropping out, I decided against going. My understanding is that original venue had union teamsters, and they required that they were the ones that hauled in supplies and set up the booths. Heard one of the manufacturers was quoted something like $17k to set up and tear down their booth. And because of that, many of them backed out, forcing the NMRA to a smaller venue.
