 Train numbers for the service are 1601 to 1616.The 6 specifies the train leaves Wellington via the Hutt Valley Line, while the 1 specifies a Masterton-bound service (2 indicates Upper Hutt, 4 indicates Taita, and 5 indicates Melling).Down services (towards Wellington) have odd numbers, while up services (towards Masterton) have even numbers

To avoid Hutt Valley passengers overcrowding the service, passengers boarding a Masterton-bound Wairarapa Connection service at Wellington and alighting before Maymorn station must pay the full fare from Wellington to Maymorn ($10.50 ).
