Narrative:

I was taxiing on taxiway Y to the west approaching runway 18L to hold short. It was raining and there was standing water on the taxiway. I was looking ahead and to the left to try to see hold short line. I also tried to see sign on taxiway Z, but an aircraft blocked my view. I looked to the right and saw the hold short sign and made an emergency stop that surprised me in the intensity of the stop causing me to let off the brakes and we rolled back. I pulled the emergency parking brake and we stopped. At that time we were definitely behind the hold short line. I don't know if we broke the hold line or not. The glare (clearing sunlight below clouds to the west) and the standing water were the cause of my inability to see the line. I did not see lights on the hold short line either. I do not think they were on. They should have been on. I will be briefing my first officer to monitor r-hand hold short signs and verbally apprise me of coasting, or if time too short to put on brakes himself. After crossing runway 18L to hold short of runway 18R the hold short lights were a big help.

Title: STANDING WATER OBSCURING HOLD SHORT LINES AT DFW RESULT IN A NEAR RWY INCURSION.

Narrative: I WAS TAXIING ON TXWY Y TO THE W APCHING RWY 18L TO HOLD SHORT. IT WAS RAINING AND THERE WAS STANDING WATER ON THE TXWY. I WAS LOOKING AHEAD AND TO THE L TO TRY TO SEE HOLD SHORT LINE. I ALSO TRIED TO SEE SIGN ON TXWY Z, BUT AN ACFT BLOCKED MY VIEW. I LOOKED TO THE R AND SAW THE HOLD SHORT SIGN AND MADE AN EMER STOP THAT SURPRISED ME IN THE INTENSITY OF THE STOP CAUSING ME TO LET OFF THE BRAKES AND WE ROLLED BACK. I PULLED THE EMER PARKING BRAKE AND WE STOPPED. AT THAT TIME WE WERE DEFINITELY BEHIND THE HOLD SHORT LINE. I DON'T KNOW IF WE BROKE THE HOLD LINE OR NOT. THE GLARE (CLRING SUNLIGHT BELOW CLOUDS TO THE W) AND THE STANDING WATER WERE THE CAUSE OF MY INABILITY TO SEE THE LINE. I DID NOT SEE LIGHTS ON THE HOLD SHORT LINE EITHER. I DO NOT THINK THEY WERE ON. THEY SHOULD HAVE BEEN ON. I WILL BE BRIEFING MY FO TO MONITOR R-HAND HOLD SHORT SIGNS AND VERBALLY APPRISE ME OF COASTING, OR IF TIME TOO SHORT TO PUT ON BRAKES HIMSELF. AFTER XING RWY 18L TO HOLD SHORT OF RWY 18R THE HOLD SHORT LIGHTS WERE A BIG HELP.
