A.3.2 For a multi-service side platform, as shown in Table C,
(a) The calculated train load is determined for each of the
side platform for both the a.m. and the p.m. peak
periods according to the formula:
[ Peak hour link load ÷ 60 x surge factor x train
headway x 2 ], and
(b) The maximum for the calculated train load shall be the
train crush load, and
(c) The entraining load for the train service that arrived at
the platform is determined for each of the side platform
for both the a.m. and the p.m. peak periods according to
the formula:
[ Peak hour entraining figure ÷ 60 x surge factor x train
headway x 2 ], and
(d) The entraining load for the other train service is
determined for each of the side platform for both the
a.m. and the p.m. peak periods according to the
formula:
[ Peak hour entraining figure ÷ 60 x surge factor x
( train headway x 2 - time lag ) ], and
(e) The transfer load between services awaiting for the train
service arriving at the platform is determined for each
of the side platform for both the a.m. and the p.m. peak
periods according to the formula (see example on the
pattern of transfer loads on platform shown in Figure 1):
[ Peak hour transfer figure ÷ 60 x surge factor x train
headway ], and
(f) The calculated platform occupant load for each of the
side platform for both the a.m. and the p.m. peak
periods is the sum of calculated train load, entraining
loads and transfer load, and
(g) Calculated platform occupant loads are determined for
scenarios based on each train service arrived at each of
the side platform, and
(h) The calculated platform occupant loads for each of the
side platform for both the a.m. and the p.m. peak
periods are compared to determine the maximum
occupant load at each platform.
