Now 109 has 2 type of new buses Citaro and Wright. Then other services ley? 163,159,112,325,372 all never get perm Citaro or Wright! They get older and more older buses? What is this? It is so unfair! SLBP buses have each buses have at least 1 or 2 perm of the new buses in each service except for 160 and Jurong Industrial Services! It is so unfair!!!!!
