Hi Guys,
I am waiting for a reply from Scott Mann of 3rd rail about this specific subject that Keystoned Ed has mentioned. That is buying a new powered 3 rail b unit from the upcoming run and connecting it to my existing powered 3 rail FP7 a unit. The information says that the new powered 3 rail b unit will be a "slave unit" that runs in conjunction with the powered 3 rail a unit. I asked Scott if this can be done and let me know what he thinks
Nick
