Over the years the format
of the Transports Citroën
timetable books varied. The orange covers of pre-war years and up until
the 1950s were eventually replaced by 1968 with the style represented
by the adjoining Réseau de Moulins booklet. The blue covers appear to
have become universal on all the Réseaux from 1971 onwards. Although it may perhaps instead have been a distinction between booklets for directly operated réseaux
and networks operated by concessionary companies. The smaller booklets
like Moulins contain third party advertisements; the blue booklets for
theréseaux did not.
Another strong operator at that time in the Moulins area was
Courriers de Bourbonnais, a subsidiary of the
GTI-VIA-Transcar group; it is believed their routes passed to Citroën.
The two routes from
the Clermont Ferrand réseau reaching into the Moulins area (lignes 3
and 9 on the map) are described in the Moulins booklet as being
operated by TCAB - Transports Citroën
d'Auvergne et du Bourbonnais;
name which no longer appeared in the 1971 Clermont Ferrand booklet,
although it was the name in use there in earlier years, at least
until 1965 (see illustration below).
