- Lionel, at least, runs on either. Older transformers were AC. newer

- so I don't know.

- Believe john said "virtually all electric trains" which leaves plenty
- of room for anomolies such as NYC. MARTA in Atlanta, the only subway
- I hope to ever get close enough to to care, uses DC on the rail with
- PWM modulated speed controllers in the cars.

- Indeed.
