National Capital Trains had two of the yellow Chessie and one of the red mid-1950s-early 1960s B&O as of 1600 Sunday at Springfield. Tex'N'Rails had one yellow Chessie and three blue B&O as of the same time/date. Both said that the red B&O 1940s-mid-1950s vanished before they could get them onto the table. Tex'N'Rails said the same about the mid-1950s-early 1960s version. NCT said that the latter were popular, but the original scheme was by far the most popular. According to the man at the FVM table, only those two vendors had them at Springfield. As of this posting, they are not at MBK, but they may have sold out before they even arrive.
The Wheels of Time B&O baggage cars also vahished quickly. I managed to get #465 and #466 from BLW, but #464 was gone from everywhere.
This proves the old saw that "All modellers and rail fans have TWO favourite roads, the B&O and one other".
