In 1975, a program for a widespread updating of the rolling stock was launched. However, as it was decided to put more emphasis on local traffic, this caused a shifting of resources from the ongoing high-speed projects, with their subsequent slowing or, in some cases, total abandonment. Therefore, 160 E.656 electric and 35 D.345 locomotives for short-medium range traffic were acquired, together with 80 EMUs of the ALe 801/940 class, 120 ALn 668 diesel railcars. Some 1,000 much-needed passenger and 7,000 freight cars were also ordered.
