A.1.7 Where trains arrive at a platform from only one direction, the “calculated train load” as used for exit calculations is calculated from the peak minute link load by multiplying by two times the headway to allow for one missed headway. The maximum for the “calculated train load” should be the train crush load. A.1.8 Where trains arrive at a platform from more than one direction, the entraining load and calculated train load for the peak direction are computed as described above. In the offpeak direction, the entraining load and calculated train load are computed from the peak minute entraining load and the peak minute link load respectively, by multiplying the headway. A.2 SINGLE SERVICE PLATFORMS A.2.1 Tables A and B illustrate the methodology for calculating the occupant load at a single service side platform and centre platform respectively. The calculations are described in A.2.2 and A.2.3 below. A.2.2 For a single service side platform, as shown in Table A, (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 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 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 and entraining load, and (e) 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.

A.2.3 For a single service centre platform, as shown in Table B, (a) The calculated train load for the peak direction is determined 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 calculated train load for the off-peak direction is determined 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 ], and (c) The maximum for the calculated train load shall be the train crush load, and (d) The entraining load for the peak direction is determined 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 (e) The entraining load for the off-peak direction is determined 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 ], and (f) The calculated platform occupant load for both the a.m. and the p.m. peak periods is the sum of calculated train loads and entraining loads, and (g) The calculated platform occupant loads for a.m. and p.m. peak, and for northbound or southbound as peak direction are compared to determine the maximum platform occupant load. A.3 MULTI-SERVICE PLATFORMS A.3.1 Tables C and D illustrate the methodology for calculating the occupant load at a multi-service side platform and centre platform respectively. The calculations are described in A.3.2 and A.3.3 below. Multi service platform occupant load calculation Standard for Fire Safety in Rapid Transit Systems A-3
