If you wish to use two separate power packs, you MUST split the load up
into two separate circuits.

You cannot just connect two packs to the same circuit, because if one
puts out slightly more voltage than the other, it will do all the work.
If one puts out SIGNIFICANTLY more voltage than the other, you will
actually create a short and burn up both packs.  Also you would have to
get the phasing correct including the effect of reversing switches.
DON'T TRY IT!

You can also consider using one pack for just accessories and one pack
for the trains - this will split the load somewhat.  If you go that
route, get a big enough unit to handle ALL your planned accessories
and use your existing pack to run the trains.
