7/12/13: This article, published on 7/11/13, now points out a completion of Line 4 automation by 2019, which is definitely more in line with the completion of the Bagneux extension. There is also a hint in the article that stock from Line 14 (Mp 89CA/MP 05) may be transferred over to Line 4, but still nothing is mentioned about the fate of the MP 89CC.
In June of 2012, I first reported about the cascading of rolling stock throughout the Paris Metro system, specifically that of Lines 1, 4, 5, and 9. A little over a year later, this latest round of cascading is nearing its final phase, with Line 9 set to get brand new MF 2001 trains beginning in September! I’ll be discussing about this upcoming transition, and following up on my previous post about the new look of the Paris subway rolling stock as we know it, in a later post. In this post however, I will be highlighting the uncertainty of my favorite Paris subway rolling stock, the MP 1989.
