the line was modernized in 1974 with the establishment of the pcc. in 1975, the sprague-thomas train model was replaced by the ma 51 model already found on line 13, with those trains eventually being replaced by the mf 67 model on 15 june 1994. line 10 is the only line, with the exception of the short 3bis and 7bis lines, that is not equipped with auto-pilot as the trains circulating at that time were not compatible with the technology. when the trains are eventually replaced with a compatible model, it is believed that the relatively low traffic of the line will not justify the investment in the installation of such a system.
