If you live in Paris, you've no doubt been hit somehow by a delayed train (perhaps even regularly). 

 

Indeed, many commuters will have been hit this week by cancelled trains as transport workers strike (again). 

 

But now we know exactly how bad the trains are in a broader sense, thanks to new figures collected by the RATP transport chiefs and the SNCF network, stats published by Le Figaro newspaper on Thursday. 

 

Beginning with the Metro, and in terms of punctuality alone, it was line 13 that performed the absolute worst in Paris. 

 

Over 2015, the line – which stretches 24 kilometres from the northern to the southern suburbs of Paris – never reached its monthly target of having 96.5 percent of trains showing up on time. In fact, at the beginning of the year over one in ten of the trains didn't show up on time. 

 

Lines 1 and 14 performed the best, which is no surprise considering they're the only two that are automated, followed by line 3, which never dipped below a 98 percent score for the year. 

 

 

When it came to peak hour traffic, the worst of all was line 9, which runs from Montreuil to Boulogne-Billancourt, and serves the Eiffel Tower via the Trocadero stop. 

 

In fact, during these peak times more than half of the city's 16 train lines didn't make the 96.5 percent punctuality goal, noted Le Figaro. 

 

Perhaps surprisingly, line 13 which was the absolute worst outside of rush hour performed among the best when it came to peak hour traffic, along with the automated services of line 1 and 14.

 

Indeed, both line 1 and 14 had near perfect scores across the board for all of 2015. 

 

On the RER lines, it was the east-west line A that performed worst in terms of punctuality. Frustratingly for commuters, it's this line that is the busiest – and is actually the busiest train line in Europe. 

 

Nevertheless, it was by far the worst train for punctuality of all the RER lines (A through to E). At its worst, in October, fewer than 80 percent of the RER A trains were showing up at stations on time. 

 

The best of the RER lines was E, which reached a top of 98.9 percent towards the end of the year. This line is the newest of the RER train lines, and has the fewest stations. It's mostly used by those living in the eastern suburbs. 

 

Lastly, when it came to the Transilien line, the worst performing was Line L, which dropped to 78.5 percent punctuality at its worst in the summer. The best lines were H, U, N and P.
