Back in the 1980’s Icoupled two N scale Halmark GP9’s together on a short straight section of track. MRC throttle, don’t rember ther model. Ran them so slow it was hard to tell they were movng. - 1ft in a little less than 10 minutes.

Good point! I hate jerky locomotive movements with a passion!

If I was going slow on the club layout, it would be usually due to bad track or another train is hogging up the mainline.
My trsin could be up front, in the middle, or behind two other trains.
