Narrative:

Parked on cargo ramp at eddf. Our clearance was a SID using runway 7, but ramp control told us to push back and face west. When we called for taxi, the mpm controller admitted his mistake, but told us to taxi forward and call ground. Ground told us to taxi to taxiway a and hold short of runway 18. He then cleared us to cross runway 18 and taxi via taxiway a and taxiway left to runway 7L. As we crossed runway 18, the ground controller said he now wanted us to turn right onto taxiway west and hold short of W1. I turned, and as I was trying to determine where taxiway W1 was, the ground controller said something to the effect of 'stop taxi' and 'stop.' he then told us to continue via taxiway west to runway 7R after the traffic landing runway 7L. I then realized that W1 was a stop line and not a taxiway. He asked us if we were past W1, and I told him that we did not see it. As we continued taxi, we did see some yellow lines marking a stop line going in the other direction. I am sure that some portion of the aircraft was past the stop line as the aircraft landed on runway 7L, so we were slightly in the path of the landing aircraft. After we admitted our mistake, the ground controller seemed to be satisfied, so I don't think he took any further action. The rapidly changing taxi instructions got me into a situation where I was not completely prepared to be, and we crossed the stop line before we knew what we were looking for. His phraseology didn't help us understand what we were looking for. Also, the stop line name and lines themselves were painted on the ground in fading yellow paint, not remarkable at all. The line is marked on the taxi diagram we had out, but since we did not anticipate going that way, we had no reason to review that taxi route in advance. There was no harm, but technically, there was a mistake.

Title: FLT CREW OF B777 CROSSED W1 HOLD LINE AT EDDF WITHOUT CLRNC.

Narrative: PARKED ON CARGO RAMP AT EDDF. OUR CLRNC WAS A SID USING RWY 7, BUT RAMP CTL TOLD US TO PUSH BACK AND FACE W. WHEN WE CALLED FOR TAXI, THE MPM CTLR ADMITTED HIS MISTAKE, BUT TOLD US TO TAXI FORWARD AND CALL GND. GND TOLD US TO TAXI TO TXWY A AND HOLD SHORT OF RWY 18. HE THEN CLRED US TO CROSS RWY 18 AND TAXI VIA TXWY A AND TXWY L TO RWY 7L. AS WE CROSSED RWY 18, THE GND CTLR SAID HE NOW WANTED US TO TURN R ONTO TXWY W AND HOLD SHORT OF W1. I TURNED, AND AS I WAS TRYING TO DETERMINE WHERE TXWY W1 WAS, THE GND CTLR SAID SOMETHING TO THE EFFECT OF 'STOP TAXI' AND 'STOP.' HE THEN TOLD US TO CONTINUE VIA TXWY W TO RWY 7R AFTER THE TFC LNDG RWY 7L. I THEN REALIZED THAT W1 WAS A STOP LINE AND NOT A TXWY. HE ASKED US IF WE WERE PAST W1, AND I TOLD HIM THAT WE DID NOT SEE IT. AS WE CONTINUED TAXI, WE DID SEE SOME YELLOW LINES MARKING A STOP LINE GOING IN THE OTHER DIRECTION. I AM SURE THAT SOME PORTION OF THE ACFT WAS PAST THE STOP LINE AS THE ACFT LANDED ON RWY 7L, SO WE WERE SLIGHTLY IN THE PATH OF THE LNDG ACFT. AFTER WE ADMITTED OUR MISTAKE, THE GND CTLR SEEMED TO BE SATISFIED, SO I DON'T THINK HE TOOK ANY FURTHER ACTION. THE RAPIDLY CHANGING TAXI INSTRUCTIONS GOT ME INTO A SIT WHERE I WAS NOT COMPLETELY PREPARED TO BE, AND WE CROSSED THE STOP LINE BEFORE WE KNEW WHAT WE WERE LOOKING FOR. HIS PHRASEOLOGY DIDN'T HELP US UNDERSTAND WHAT WE WERE LOOKING FOR. ALSO, THE STOP LINE NAME AND LINES THEMSELVES WERE PAINTED ON THE GND IN FADING YELLOW PAINT, NOT REMARKABLE AT ALL. THE LINE IS MARKED ON THE TAXI DIAGRAM WE HAD OUT, BUT SINCE WE DID NOT ANTICIPATE GOING THAT WAY, WE HAD NO REASON TO REVIEW THAT TAXI RTE IN ADVANCE. THERE WAS NO HARM, BUT TECHNICALLY, THERE WAS A MISTAKE.
