Narrative:

I was providing OJT on local control. Traffic was building with numerous aircraft in the north and south patterns. I asked the controller in charge to split the local control position. It took him a couple of minutes as he was working on an IFR release for us and attempted to take a briefing but it was too busy to brief. I told the developmental working to make his pattern players full stop so that we could brief and start fresh. Aircraft X was cleared for a full stop landing on ryxxl; number one. Aircraft Y was cleared to land ryxxl; number two; following aircraft X. Spacing was close; so the developmental told aircraft Y that 'south turns' south of course were approved for spacing; hoping that the pilot would make them and adequate spacing would be achieved. We moved on to other traffic and by the time my scan made it back to ryxxl aircraft X had landed approaching a turn of south of the runway at taxiway P; closely followed by aircraft Y who had already landed and rolled out. I instructed aircraft X to exit the runway immediately and aircraft Y followed him off at taxiway P. I should have shut down the pattern and then reconvened once we were able to split the local position. I also could have taken over for the developmental at a point where we had decent control over the traffic; it had developed to a point that we were reacting and the situation was chaotic. I do have to mention that the staffing levels are low and would greatly benefit from more controllers so that we could have the local control position split.

Title: Tower Controller and Controller In Charge reported a runway incursion after attempting to land all aircraft due to workload and splitting Local Control.

Narrative: I was providing OJT on Local Control. Traffic was building with numerous aircraft in the north and south patterns. I asked the CIC to split the Local Control position. It took him a couple of minutes as he was working on an IFR release for us and attempted to take a briefing but it was too busy to brief. I told the Developmental working to make his pattern players full stop so that we could brief and start fresh. Aircraft X was cleared for a full stop landing on RYXXL; number one. Aircraft Y was cleared to land RYXXL; number two; following Aircraft X. Spacing was close; so the Developmental told Aircraft Y that 'S turns' south of course were approved for spacing; hoping that the pilot would make them and adequate spacing would be achieved. We moved on to other traffic and by the time my scan made it back to RYXXL Aircraft X had landed approaching a turn of south of the runway at Taxiway P; closely followed by Aircraft Y who had already landed and rolled out.
