The fourth metro line currently under construction in Budapest has been continually delayed. First it was lack of funding, then the EU cut back on additional funding due to the inefficiency of the work being done. Although it was projected to be completed in 2010, they say it may take longer since the drills are not as efficient as they first thought. Perhaps it is the drillERS that are not as efficient. This video was taken at Keleti train station. I know each time I am in any area where Metro 4 construction is going on, I have yet to see actual work taking place.
