I always thought I ran too slow....now I see I am in the middle of the pack with you all. Anywhere from 18 to 30 MPH via the DCS handheld. Depends on how many at once and how long.
Today, I had an 3 engine MU w/ 18 PW Lionel cars from childhood pulling on one loop at 25 and another unit running at 20. I always thought it was cause I was old, now I know it is because I am old and need to concentrate to keep them from hitting each other if I run over two trains at once!
