A number of players asked to see the weapons firing on the locomotive, so I've added that.
I've added the option for you to buy additional supplies before starting a level. Each additional supply costs $500. You can purchase a maximum of 20 upgrade pallets or whatever number you have enough money for less than 20. You are only billed when you select a level. When the level starts you'll find that you have the additional purchased upgrade pallets plus whatever you've unlocked through the ability unlock menu. I think this is important for being able to conquer Hard Mode. You're a train so of course you should be able to take some supplies with you!
The crusher has been improved so that it not only hurts the enemies but now reduces the slowdown caused by zombies. With a fully upgraded crusher you can really feel the power of the locomotive as it wades through the zombie horde crushing them beneath its mighty wheels.
From here on I'll be moving to a fortnightly or monthly schedule for significant game content updates. I'll still be doing smaller patches in between for bug fixes and tweaks to the game.
Here are the other launch week updates I've done that you may have missed:
