(a) whether the concept of higher utilisation of rake capacity with decreased turn-around
time was extended to passenger services as well ;
(b) if so, whether without adequate investments in acquisition of new rolling stock,
several daily mail/express train services that earlier utilised four rakes are now being
running on three rakes leading to curtailment of stipulated turn-around time for cleaning and
maintenance services ;
(c) if so, whether this curtailment of turn-around time has led to dirty trains pressed
into service from originating stations; and
(d) if so, the corrective steps being taken in this regard?
