I just purchased a Williams E7 AA set from a forum member who had upgraded it to TMCC and RS using a TAS board. I am not sure what board he used but it really needs cruse on my layout. The amount of curves and my grade on my layout make it almost impossible to run at a slow speed.
Can all the TAS boards be upgraded with TAS EOB or only certain ones? Are ERR boards compatible with TAS boards or will I need to change the whole thing out? Is it an easy upgrade?
