Z21 router question

[Pete Williams]

I have a roco H0/e 'start' set which includes  the plain black control unit and a cable tethered multimous.
My questions are, will this box work with the dedicated z21 router, or wil i have to buy the z21 control box, as well?
If the latter, will the kit-supplied power-pack be man enough to power the z21?
