The issues that generally limited a USRA 0-6-0 to yard switching were:
- lack of a big enough firebox to generate enough steam for steady steaming. Yard switching has a lot of "stopped" time to recover steam pressure.
- small drivers and lack of sophisticated balance prevented speeds above 25MPH. This would particularly impact use in passenger service.
- lack of enough water and fuel capacity to go very far (could be fixed with a bigger tender)
