How to beat Railgun on last level?

[StEx]

I tried it few times. Until railgun arrives my Toybox is perfecly safe. But I don't know how to deal with Railguy. There is only 3 position from which I can damage it (2 side by side in center of the map and one right above tunnel exit). I built 3 mortars and fully upgrade it. Then man the tank and continiusly firing at train. And I can't do anything. Train enter scene 3 times, I can't destroy it in this time. And on forth time it just rammed my toybox. I dont' understand with what I can do more damage on Railgun.

Way to post spoilers you selfish boy.

You need to add a level 3 Howitzer on that thing. There is a spot for one on the right side of the map that you can angle towards the railgun when its moment arrives. And then make sure to have another level 3 Howitzer on the spot further back in case you need it to help out if the railgun charges forward and is almost dead. Also, I know a lot of people use the tank to help damage the railgun but I personally use the bomber.

I beat it with tank. Left tank is very powerful and can hit train almost from spawn place.

Use the tank. That way you don't have to worry about the smaller vehicles that come from the tunnel when the train retreats after each attack. You can destroy everything that comes your way from the the railway track. Howitzer's and level 3 mortars help too.

Small vihicles easily destroyed but 3 lvl 3 Mortars in center of level.
Tank is the key to victory. Or bomber, as 5hark sayd.

BTW, I finish all modes (on normal) and earned all steam achievments. So if anybody get stuck with something, I can help %)
