Freshly Painted B&M/Pan Am Boxcars UPDATE

The latest batch of repainted Pan Am boxcars are roaming the rails.  The first ones spotted were simply dark blue with "BM" reporting marks.  Then I spotted one with PAN AM block lettering and an American flag.  On 7/17/12 I spotted this car, #3316 with the full Pan Am logo.  I don't know if the same style is on the other side.

#3345 with no Pan Am logos 7/6/12

#3388 with block logo 6/27/12
