Piggybank Wagon

Handbook description

Fill the piggybank with wood or iron to collect bolts!

Strategy

Piggybank is a special wagon that can only be 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 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.

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. The following chart shows how long it would take to make back the investment on upgrading the piggybank.
