Narrative:
I was about #7 or 8 for takeoff at midway airport in line on the taxiway leading to runway 22L. I was following an medium large transport in front of me and was creeping up behind him, getting closer to the end of the runway. Because of the extensive ground delay, I asked tower how much longer. He advised, 'a few minutes, pull up behind the medium large transport, you'll be going right out'. As I got closer to the end of 22L, and the medium large transport ahead of me took the runway, I wondered where the hold line was. As I pulled up closer to 22L, and the medium large transport took off, I saw a solid yellow hold line (not dotted) which I held behind. When we were cleared into position on 22L, I saw another medium large transport holding behind a standard dotted and solid yellow hold line about 200' behind me. I began to wonder how it was that I didn't see it. The reason was, because the 1ST medium large transport I was told to follow was covering the line the whole time, hiding it from my view.

Title: FLT CREW OF LGT CONFUSED REGARDING TWO HOLD LINES APCHING RWY 22L AT MDW.
Narrative: I WAS ABOUT #7 OR 8 FOR TKOF AT MIDWAY ARPT IN LINE ON THE TXWY LEADING TO RWY 22L. I WAS FOLLOWING AN MLG IN FRONT OF ME AND WAS CREEPING UP BEHIND HIM, GETTING CLOSER TO THE END OF THE RWY. BECAUSE OF THE EXTENSIVE GND DELAY, I ASKED TWR HOW MUCH LONGER. HE ADVISED, 'A FEW MINUTES, PULL UP BEHIND THE MLG, YOU'LL BE GOING RIGHT OUT'. AS I GOT CLOSER TO THE END OF 22L, AND THE MLG AHEAD OF ME TOOK THE RWY, I WONDERED WHERE THE HOLD LINE WAS. AS I PULLED UP CLOSER TO 22L, AND THE MLG TOOK OFF, I SAW A SOLID YELLOW HOLD LINE (NOT DOTTED) WHICH I HELD BEHIND. WHEN WE WERE CLRED INTO POSITION ON 22L, I SAW ANOTHER MLG HOLDING BEHIND A STANDARD DOTTED AND SOLID YELLOW HOLD LINE ABOUT 200' BEHIND ME. I BEGAN TO WONDER HOW IT WAS THAT I DIDN'T SEE IT. THE REASON WAS, BECAUSE THE 1ST MLG I WAS TOLD TO FOLLOW WAS COVERING THE LINE THE WHOLE TIME, HIDING IT FROM MY VIEW.
