BN SD40-2 7821 followed second in the classic BN scheme.
Once all three units were in view we could see the third unit was one of the 2 LNG units BN tried out on it's coal drags. The experiment was over by this time and the fuel tenders were gathering dust.
I remember the day, it was over 90 degrees out, I can see the engineer had the rear door open to get a little airflow in the cab. This was well before AC was standard from the factory.
As they roll away I see the classic line of the BN 7821 again. I can still almost hear them rolling by, all pushing a quick notch 6 through the swamps.
The BN 7821 and BN 7151 are a couple samples from my friend HK's collection of finely detailed and painted BN and DMIR engines. The 7890 has headed from the Skally shops to join its brethren in HK's fleet.
