sv25 have SDs due to the route it serves has other svcs to cover
for the "drop" in capacity if sv25 SD arrives, ie 55,854
sv99 partial route covered by sv198, further more SBST thinks more
people wld travel by train from JE West st to Cle
sv241 short distance trip, no need full DD fleet
sv72 is the one where full DD fleet is required
sv25 have SDs
due to the route it serves has other svcs to cover for the "drop"
in capacity if sv25 SD arrives, ie 55,854 [ I feel s25 has
loading throughout its route. Most times it has +100 pax on AMK Ave
3, high loading from HG Ave 2/3 to Eunos Link. The only part where
pax is low is between Eunos to Bedok. Whenever a SD comes, it is
packed to brim. ]
sv99 partial route covered by sv198, further more SBST thinks more
people wld travel by train from JE West st to Cle [ s99
route is not really covered by 198. It goes through Jurong Ave 4/5,
st 91/92, Boon Lay Place, Corporation Drive and is the only route
connecting different parts of Jurong areas. It is like an
intra-town. Again, most pax take it from Synergy / IBP to Clementi.
It has high loading for full route. Hence, full DDs required.

sv241 short distance trip, no need full DD fleet
[
Each route of s241 is totally packed. But yes, it is okay if a few
SDs are deployed, because it is a short route.
]
sv72 is the
one where full DD fleet is required [Apart from 72B, where
SDs should be used, for 72A and 72 only DDs should be
used]
