On 8 July 1991, route 1 replaced route 3, making route 1 Cormondrèche–Place Pury–St. Blaise–Marin, and the Place Pury to Serrières section was taken over by route 7.Trolleybus Magazine No. 180 (November–December 1991), pp. 129, 149. On 29 May 1994, route 7 reverted to operating Place Pury–Hauterive, and the designation route "2" was revived for the Place Pury–Serrières section. At the opposite end of route 7, the trolleybus wires were extended from Hauterive to Marin, for access to a new depot opening there in September 1994, and starting on 3 October 1994 three route 7 trips per day operated through to or from Marin.Trolleybus Magazine No. 199 (January–February 1995), p. 27. In June 1996, route 7 began serving Marin at all times and days except evenings and Sundays, but with half of its scheduled non-rush-hours trips still terminating at Hauterive.Trolleybus Magazine No. 209 (September–October 1996), p. 127.
