Narrative: I was training someone on Ground Control 1. Trainee told Aircraft X to taxi to [Runway] 25R via C10. I saw Aircraft X entering [Runway] 25R via N with an air carrier on departure roll. I overrode my trainee and said 'Aircraft X stop;' three or four times until they stopped. The departing aircraft needed 30 plus minutes to cool their brakes. This is the third time an aircraft has tried to enter [Runway] 25R on me in the last two or three months. The other two were aircraft taxing to [Runway] 24L via C10; B; P; north route. They both turned at P onto [Runway] 25R. If you look at the map a left turn at P makes no sense. There are wigwag lights alerting the pilot of the runway and two giant [Runway] 25R/7L signs painted on the ground. I understand the need for construction at an airport; but LAWA [Los Angeles World Airports] doesn't care about the impact. Monthly runway checks are done during the day; and this closes a runway for 30 plus minutes. This absolutely crushes everyone in the Tower; it is always a complete mess; planes everywhere; just stupid. Another closure LAWA loves to do is close Runway 24L; 10 minutes before all the A380 night departures go; this means they need to taxi to [Runway] 25L (have you seen all the restrictions for this thing?)The 'quick' reference guide is far from quick. LAWA needs to escort them everywhere; etc. Last Friday an A380 broke on Taxiway 'E' blocking two other A380's from taxiing; blocking several other aircraft; just stupid. This was being worked by a Supervisor; on the log; combined with Clearance Delivery. She could barely work Ground Control no less Clearance Delivery and answer the telephone and coordinate the [Runway] 24L closure. The airport is still busy as hell [very early in the morning] and we have to combine positions because people are at the end of their 10 hour shift.LAX is super understaffed; way over worked; we are nearing crisis here. Nobody can certify because the airport is so messed up with restrictions and push backs on taxiways; volume; SCT's inability to stay off the inboards and LAWA's continued lack of understanding of the impact of their crappy airport design (which; by the way; is only being perpetuated by their future construction design.) I could go on and on; is anybody listening out there?


Second narrative: We had pushed off gate at LAX on to taxiway C. Taxi instructions were [Runway] 25R C10 Bravo. We both heard the instructions. [We] talked about where we were going and pointed to where we were going. As we started to move I checked to make sure everything was clear.I then looked down to check on our close-out. I looked back up something didn't look right. Both of us recognized the problem at the same time. The Captain was stopping the aircraft at the same time Ground Control was saying stop. The aircraft stopped over the hold short line but short of the actual runway. We then were cleared to taxi to the runway for takeoff. Flight was then completed normally.


Synopsis: Five reports of a runway incursion at LAX where a taxiing aircraft entered the runway environment on the way to a runway; causing a departure to have to be aborted.
