I agree. Three rail O has certainly helped both 2 rail O and S.
I found this video on You tube.
What company made the EM-1?
And that other thread where you showed the link to the video of that Y3 which was converted to scale flanges and DCC. I wonder does anyone else do these type of conversions? And they said that to convert to DCC was just software do you think it is possible to convert other Lionel locomotives to DCC by changing the software? If yes, they should sell the program to us folks instead of a $75 charge for each engine. This way one does not have to send every locomotive through the mail.
