Forum:Are Pre-Time War Daleks and Time Lords time locked as well?

It has been made clear in the New Series that the Time War is time-locked. So the Doctor can't go back to Gallifrey. But, since he encountered his pre-Time War self in Steven Moffat's Time Crash, could he meet up with other Time Lords who haven't experienced the Time War yet?

Fuguritively speaking, if the Tenth Doctor went back to see the Fourth Doctor, could he hitch a ride on the Fourth Doctor's TARDIS to visit a pre-Time War Gallifrey?

Likewise, could a New Series Doctor meet up with the Classic Series Daleks?

Isn't there a plot device that prevents either scenario above from happening?
