Piggybank Wagon
Handbook description
Fill the piggybank with wood or iron to collect bolts!
Strategy
This wagon is obtained at the ??? Station of Monorail Meadows Biome.
Piggybank is a must have for your run due to the amount of bolts it can generate.
It is most efficient to upgrade the piggybank to level 4, then apply two 
supercharge extensions onto the piggybank. The sooner you upgrade the piggybank, the more bolts it can generate for you in your run.
It is a very bad idea to apply the 
storage-pull extension on the piggybank as it can quickly drain your stack of resources. Instead, you can put 
magnet-pick extension on the piggybank. This way, you can start pilling up resources near the station at the end of the level, and the piggybank will automatically consume them all on the next level if the resource aren't used.
