新加坡車務 一問

話説小弟過幾日將會去新加坡玩，尤其想遊下巴士河，有幾個車務問題想問下——
I will be visiting Singapore a few days later, especially targetting for some bus rides. I would like to ask a few questions about the bus service——

1. 呢幾日喺度試iris，發現一到禮拜六日，啲無輪椅位車(i.e.豪)好多都唔出車。係咪一直以來都係咁？
另外，除咗文禮之外，有無其他地方會比較容易搭中豪？
1. I've been trying out the iris app this few days, and discovered non-WABs (i.e. Volvo Olympians) are usually out of service on weekends/holidays. Is this a common practice?
Besides Boon Lay Int., are there any places that i could have higher chance riding Volvo Olympians？

2. 想問呢兩部樣板車(三門 A95 SG5999Z 及 CDGE B10TL SBS9889U)有否固定的兩邊開車時間？如有，能否提供？
2. Are there fixed departure times for the 2 demonstrators (3-door A95 SG5999Z & CDGE B10TL SBS9889U)? If so, could you provide the timetable?

3. 在SgWiki嘅巴士掛牌表註腳，紅綫間住嘅E/S/N/T等係代表咩？
3. Under SgWiki Bus Deployments' Notes, what does the underlined E/S/N/T(.etc) mean?



4. 大家有無一啲遊車河嘅路綫推介？
4. Are there any recommended bus routes for a joyride?


先感謝幫忙！
Thanks for your help in advance!

SG5999Z既時間日日不同...但我既經驗2,3點會返Jurong east
