If you take a long hard look at the screeny you can get the gist of it.
However some specifics:
Put the TF one length away from the tram, and all seiges should reach nicely assuming they are on the wall closes to the hive.
Watch for lerks, the vents were reworked to allow a alien friendly system that isn't along they painfully long tram tunnel, so be sure to watch for flanks.
If they aliens start with tram you can relocate to lower junct and seige at the very begining, just make sure to have 1 marine capping other nodes, and run the tech tree as lerks will pester soon enough.
