History
When Link and Zelda head to the Ocean Realm to fix the third part of the Tower of Spirits, they find the bridge is out. Making a quick stop at the Trading Post to ask around, they meet Linebeck III, who informs them that a bridge builder lives in the Snow Realm, and should be able to fix the bridge easily.

After Link and Zelda successfully transport the builder, he reveals that the price of the bridge, as well as the repairs on Linebeck's house he did a while ago, should add up to five-thousand Rupees. Linebeck, shocked at the price, enlists the help of Link to gather up the money. He gives the hero a letter from his grandfather, written before his death, that leads to the location of his last piece of treasure: a Regal Ring.

When Link returns with the ring, the bridge builder takes it to pay Linebeck's debt, and from that point Linebeck III will buy off Link's treasure, and trade for train parts as well.
