The Great Train Robbery – Silver Streak Achievement
The trick to the Great Train Robbery is to build a ton of Diamondbacks, expand to to the north to gather more resources and avoid the Marauders that are patrolling later in the game. Be relentless with your Diamondback production and build a group of Marines and Medics for additional support. I used 2 bunkers at my main base for defense; this was in case I was caught off guard. Stay on top of Supply Depots from the start, build two Engineering Bays and upgrade your Diamondbacks to 2/2 at your Armory.
At the start of the round, start collecting the lost Diamondbacks. This will use up your Supply Depots, so start building them right away. Here is a map of the locations:
The Great Train Robbery Diamondback Locations
Pay attention to the ‘Next Train’ timer and be ready to attack. Otherwise, keep your units at your base. On the 7th train you need to go counter clockwise behind the Marauders or they will cut you off as you chase the train from left to right. See the video for more details.
Silver Streak: Complete the Mission without letting a train pass on Hard mode.
This achievement equates to completing the mission without screwing up. Watch the videos again if you’re still having problems.
Bully the Bullies: Kill the Marauder Kill Team on Normal difficulty.
I did this on Hard mode, accidentally. Right before the 8th train your army should be so massive that you can afford to overrun the Marauders without issue. This is when I recommend you take them down. Do it on Hard mode, no need to do the map a second time just for this achievement.
The Great Train Robbery: Complete all Mission Objectives
Use the Diamondback locations above and you’ll see the skeletons show up on your map as the map is revealed by the Marauders and the trains. I forgot to get the last one in the video.
