True for trailing point turnouts, but facing point turnouts can be more problematic, depending on the brand of 2-Rail Scale trucks. I tend to prefer the Weaver 2-Rail freight trucks as a first choice, with the MTH 2-Rail freight trucks second. Both of those brands tend to have slightly wider treads, and thus work better thru the Atlas turnouts, in either direction, once the guard rails are raised.
