Narrative:

The first officer called stl ground for taxi out request. We received clearance and instructions to taxi to runway 12L via taxiway D, runway 6 and hold short of runway 12R. We held short of runway 12R. We were then given clearance to continue taxiing to runway 12L. As I was slowing the aircraft to stop on runway 6, stl tower told us to hold our position and informed us we had crossed the hold short line. After several seconds, stl tower then directed an aircraft on final to go around. Neither the first officer nor myself saw the hold short line on runway 6 until tower mentioned it to us. We could then see it right beneath us after we stopped. The painted lines on runway 6 appeared to need repainting. Runway 12L does not physically intersect with runway 6, and so we were not expecting to see hold short lines on runway 6. Another aircraft was taxiing abeam us on taxiway C to runway 12L. We had the impression that we were using runway 6 as a temporary taxiway to bypass the traffic on taxiway C (the normal taxi route to runway 12L). Due to this perceived taxi 'plan' and the faded hold short lines, we did not see or expect to see, the hold short lines on runway 6.

Original NASA ASRS Text

Title: MLG CREW HAD RWY INCURSION AT STL.

Narrative: THE FO CALLED STL GND FOR TAXI OUT REQUEST. WE RECEIVED CLRNC AND INSTRUCTIONS TO TAXI TO RWY 12L VIA TXWY D, RWY 6 AND HOLD SHORT OF RWY 12R. WE HELD SHORT OF RWY 12R. WE WERE THEN GIVEN CLRNC TO CONTINUE TAXIING TO RWY 12L. AS I WAS SLOWING THE ACFT TO STOP ON RWY 6, STL TWR TOLD US TO HOLD OUR POS AND INFORMED US WE HAD CROSSED THE HOLD SHORT LINE. AFTER SEVERAL SECONDS, STL TWR THEN DIRECTED AN ACFT ON FINAL TO GO AROUND. NEITHER THE FO NOR MYSELF SAW THE HOLD SHORT LINE ON RWY 6 UNTIL TWR MENTIONED IT TO US. WE COULD THEN SEE IT RIGHT BENEATH US AFTER WE STOPPED. THE PAINTED LINES ON RWY 6 APPEARED TO NEED REPAINTING. RWY 12L DOES NOT PHYSICALLY INTERSECT WITH RWY 6, AND SO WE WERE NOT EXPECTING TO SEE HOLD SHORT LINES ON RWY 6. ANOTHER ACFT WAS TAXIING ABEAM US ON TXWY C TO RWY 12L. WE HAD THE IMPRESSION THAT WE WERE USING RWY 6 AS A TEMPORARY TXWY TO BYPASS THE TFC ON TXWY C (THE NORMAL TAXI RTE TO RWY 12L). DUE TO THIS PERCEIVED TAXI 'PLAN' AND THE FADED HOLD SHORT LINES, WE DID NOT SEE OR EXPECT TO SEE, THE HOLD SHORT LINES ON RWY 6.
