2. 5.2. As the expected range of frequency As the expected range of frequency of
of acceleration at axle and bogie level is acceleration at axle box is up to 500 Hz
up to 250 Hz, The sampling frequency and bogie level is up to 100 Hz, The
of acceleration shall not be less than sampling frequency of acceleration shall
the 2.5 times of the expected maximum not be less than the 5 times of the
frequency. Thus the sampling expected maximum frequency. Thus the

hours, at terminating base stations
specified in clause 7.2 and 7.3, a
penalty of Rs. 5000 per additional 24
hours or part thereof will be levied for
the systems for which fault has been
detected remotely.
 9.1. The cloud based system/
processing station should have an up-
time of better than 99.5% i.e. an
unplanned downtime
of less than 44 hours per annum.
Occurred failures of the cloud based
system/processing station exceeding 44
hours per year will attract a penalty of
Rs 5000 per hour.
9.2. The cloud based system or
processing station shall be designed to

9.3. The firm is required to provide a
user support helpdesk during user
working hours (9 AM to 6 PM IST) six
days a week except Sunday. Access to
support system should be available
through telephone and email.
9.4. The firm is required to provide
training to user to access data/
information/ reports available at cloud
based system or processing station. The
training shall be initially given to
a group of users. Subsequently trained
user will further give the training to
other users.
