This thread reminds me of an older model railroader in the area who
judged the quality of his locomotives almost solely by how fast they
would go, and whether they would go forward and backwards at the exact
SAME speed. He'd crank the voltage up to 12 volts and TIME the loco as
it whizzed around the table type layout, first one way, then the other.
His curves were 22" radius at most, likely more like 18". It was quite a sight.
When visiting him one day he put on such a demonstration for a friend
and I. After watching several favorite locos 'perform', he reached his
AHM (Rivarossi) GG-1, which went so fast it flew off the layout and hit
the WALL. Needless to say we were impressed! :-(
When we left, my friend suggested a 'loco quality meter' could be built
that consisted of a yardstick taped to the wall. The quality of a loco
could then be quantitatively judged by how HIGH on the wall it hit when
it flew off the layout. Those that only hit the floor were definitely
Takes ALL types!
