During normal playthroughs of this mission, you are not required to push into enemy bases. However, if you would like to finish the mission in the fastest possible time, or find that you are bored idling, you can push into the two bases on the left of the map to spawn-camp the trains.

The main objective will either spawn on the top rail or the middle rail. The paths these main objectives will take is shown below.

Spawn Points

The spawn points for attack waves and escort waves are different.

The attack wave gather points are dependent on which side the attack wave comes from. The Northern gather point is shown below. This is, in essence, the start of the top rail.

Northern Gather Point

The Southern gather point is shown below. This is, in essence, the end of the bottom rail.

Southern Gather Point

Train escorts all have a single spawn position before they spread to guard the train. The spawn positions of the ground escorts are right outside the little warehouses on the map. All units, including air units spawn at these warehouses. However, after roughly 8 seconds, they will teleport to the Air Spawn point, a little distance away.

For the top rail, the spawn points for the escorts are shown below.

For the middle rail, the spawn points for the escorts are shown below.
