Then if you just miss bus and is 2 bus come together then good luck
i told Sev 51 from JE to HG i told a DT 3 (SBS9688H) will the way and guess what the bus can catch up 4 bus in front and behind my bus was also a DT 3. When it got to HG there was 6 Buses
From JE:

2 Leyland Olympian 3-Axle
3 Leyland Olympian 3-Axle
4 Dennis Trident 3 (SBS 9688 H) (i told this bus)
5 Dennis Trident 3

1 Dennis Trident 3
2 Dennis Trident 3 (SBS9688H)
3 Leyland Olympian 3-Axle
4 Leyland Olympian 3-Axle
