If you are interested to take part in a similar service this year on Remembrance Sunday, I have found out from the Singapore St. Andrew's Society's website the following information on the service:

To get to the Kranji War Memorial, unless you are an important invited guest who will be given special access passes to drive into the Kranji War Memorial, I highly recommend you travel to the War Memorial using any one of the following methods:
1) Take the MRT train to Kranji MRT station. Either walk or take bus services number: 160, 170, 178, 960, 961 to bus stop #45119 (two bus-stops away) along Woodlands Rd. Take a 10 -15 minutes stroll into the Kranji War Memorial.

Attire wise, you may like to take note that even though there is no specified dress code, I had observed that most of the guests will be wearing uniforms or formal attire for the service.
