<s>[INST] The next text is a question of a member of the European parliament:"SMA, the highly regarded Swiss rail timetabling company, has issued an opinion stating that the Stuttgart21 project is inefficient. In its issue No28 of 2010 the magazine Stern reports that this opinion is being withheld by the German Ministry of Transport.   In this connection, the Ministry also seems to want to keep the recalculation of costs for the new Wendlingen–Ulm line under wraps until demolition work at the current main station in Stuttgart is complete, thus creating a fait accompli. According to the abovementioned source, this new line is supposed to be considerably more expensive than the previous EUR2billion estimate.  Is the Commission aware that — as reported by radio broadcaster Hessischer Rundfunk as long ago as 25July2007 — Wolff & Müller, the company contracted to demolish the current main station in Stuttgart, is not paying the standard minimum wage for the construction industry in Baden-Württemberg?  Further evidence for this is the fact that on 4February2006 this company had to pay 19 Romanian construction workers an additional EUR21000 under pressure from the German trade union IGBAU."
