Reply to "1:48, 1:50, but will1:64 work with O guage?"

I am an S scale collector/operator and have a lot of 1/64 cars and trucks. I would not use them on an O scale layout. The 1/64 cars have a lot less detail, there are far fewer prototype car models to choose from and they are way undersized for O scale. As mentioned above some of the Plasticville is undersized so sometimes a 1/64 vehicle looks right with Plasticville, sometimes not. Also as mentioned above, forced perspective can be a good application if they are not within reach of the viewer.
