layout query... should i or shouldnt i?

some are you are familiar with my christmas layouts featuring plarail/trackmaster etc.

this year, lego released a christmas train, which i have bought and fitted with 9V. i dont have a huge amount of 9V track, and cant afford to buy more right now. should i also do my usual tomy running around the outside? could do the lego train running one direction, and thomas running the other.

after last years dramas, the tomy layout will be basic, maybe using the transfer station, but will have to wait and see.

this will all come down to the size of the table, but i think it would work if i cut down on the amount of junk filler used.

so, what say you, members of BPT?
