Narrative:

After pushback, we were cleared by ground control to taxi from ramp to 'taxi to runway 28.' I expected the captain to taxi txwys east and P to runway 28. Everything was routine and there were no internal/external distractions up to the point we nearly entered runway 28 at taxiway east. On taxiway east, as the nose of our plane crossed perpendicular to the taxiway P centerline, I recognized the captain was not going to turn. I immediately told him to stop, which he did. Ground control called us, told us we'd missed our turn, and asked if we'd crossed the hold short line. We were very close, and I wasn't sure. I said we were close, maybe on top of it. An air carrier aircraft on taxiway P called ground and said we were not across the hold short line. A runway incursion had not occurred, but not by much. We were subsequently cleared to back taxi onto runway 28, turn off at the next intersection, and back onto taxiway P. The subsequent taxi, takeoff, and departure were accomplished without incident. The problem was caused by, 1) the captain expressing his familiarity with the airport and not confirming our taxi route with the airport diagram, 2) me not verbalizing the route to the captain, 3) the close proximity of the runway to the taxiway at that intersection, and 4) ground control not specifying a taxi route to the runway. The captain and I discussed what went wrong, and we each learned something valuable. I think this is a particularly dangerous intersection. On a bright, sunny day, yellow lights aren't very effective. There should be red stop lights marking the runway hold short line (or flashing red lights of some sort). Finally, ground control should be stating the taxi route to our departure runway (air carrier X, taxi txwys east, P to runway 28).

Title: B757-200 CREW ALMOST HAD A RWY INCURSION OF RWY 28 ON TXWY E AT BWI.

Narrative: AFTER PUSHBACK, WE WERE CLRED BY GND CTL TO TAXI FROM RAMP TO 'TAXI TO RWY 28.' I EXPECTED THE CAPT TO TAXI TXWYS E AND P TO RWY 28. EVERYTHING WAS ROUTINE AND THERE WERE NO INTERNAL/EXTERNAL DISTRACTIONS UP TO THE POINT WE NEARLY ENTERED RWY 28 AT TXWY E. ON TXWY E, AS THE NOSE OF OUR PLANE CROSSED PERPENDICULAR TO THE TXWY P CTRLINE, I RECOGNIZED THE CAPT WAS NOT GOING TO TURN. I IMMEDIATELY TOLD HIM TO STOP, WHICH HE DID. GND CTL CALLED US, TOLD US WE'D MISSED OUR TURN, AND ASKED IF WE'D CROSSED THE HOLD SHORT LINE. WE WERE VERY CLOSE, AND I WASN'T SURE. I SAID WE WERE CLOSE, MAYBE ON TOP OF IT. AN ACR ACFT ON TXWY P CALLED GND AND SAID WE WERE NOT ACROSS THE HOLD SHORT LINE. A RWY INCURSION HAD NOT OCCURRED, BUT NOT BY MUCH. WE WERE SUBSEQUENTLY CLRED TO BACK TAXI ONTO RWY 28, TURN OFF AT THE NEXT INTXN, AND BACK ONTO TXWY P. THE SUBSEQUENT TAXI, TKOF, AND DEP WERE ACCOMPLISHED WITHOUT INCIDENT. THE PROB WAS CAUSED BY, 1) THE CAPT EXPRESSING HIS FAMILIARITY WITH THE ARPT AND NOT CONFIRMING OUR TAXI RTE WITH THE ARPT DIAGRAM, 2) ME NOT VERBALIZING THE RTE TO THE CAPT, 3) THE CLOSE PROX OF THE RWY TO THE TXWY AT THAT INTXN, AND 4) GND CTL NOT SPECIFYING A TAXI RTE TO THE RWY. THE CAPT AND I DISCUSSED WHAT WENT WRONG, AND WE EACH LEARNED SOMETHING VALUABLE. I THINK THIS IS A PARTICULARLY DANGEROUS INTXN. ON A BRIGHT, SUNNY DAY, YELLOW LIGHTS AREN'T VERY EFFECTIVE. THERE SHOULD BE RED STOP LIGHTS MARKING THE RWY HOLD SHORT LINE (OR FLASHING RED LIGHTS OF SOME SORT). FINALLY, GND CTL SHOULD BE STATING THE TAXI RTE TO OUR DEP RWY (ACR X, TAXI TXWYS E, P TO RWY 28).
