I use DCC filters/Snubbers on my DCC Bus. My Bus cables supply power to the track and to my twenty five Cobalt Digital point motors. I do not have a separate bus for the points. I also have a DCC Concepts Power Boost - so a 5amp supply (this is a recent addition). I have not found any problems in just using one pair of bus wires - I am not changing points every other second, so no extremes of power being used while loco's are running. In some ways my layout is set-up as DCC was originally reported "Just two wires to the track", and all loco's and points can be operated via my Hornby Elite controller - I also use HM7000 with my iPhone. Also my layout is an end-to-end, so I do not have loco's running continuously around a layout. The choice is yours.

The case for a split bus was 2 fold: first if a derail say by a wrongly set point occurred the point could be reset, the track restored and away you go; second there have been reports of track bus spikes damaging some acc decoders.
A decent workaround for a single command station is to run the track bus thro' a circuit breaker in parallel with the acc bus, both connected to the one controller.
