I read somewhere that ground throws are on the curved side of the turnout. Is this true? I have no room on some of my turnouts to put a throw bar on the straight side.
Do what you have to do.
Switch stands are placed where they will be safest to operate. For example, in a typical yard ladder, the switch stands will be on the straight side so that employees don't have to cross the tracks to get from one to the next.
On a 'pinwheel' ladder, the switch stands would be on the curved legs.
'Generally,' they will be on the straight side, but there's a prototype for everything.
If you're using Atlas turnouts, it is easy to reverse them as joed said. I have done it on about 25% of my layout. While I usually do it because of clearance issues, there are a few that I did so I wouldn't have to reach over things to operate them.
