[3] During the Early Middle Ages, the Abbey of St. Gall owned much of the land around Bussnang.

In 1529, the parish was converted to the Reformation by Johannes Zwick, though mass was re-instituted in 1596.

The sectarian clashes were relieved but not settled with the so-called Rosenbach'schen Treaty of 1639.

Later, a ferry operated until 1453 when a bridge was built in Thurrain (part of Rothenhausen).

However, through the following centuries traffic remained light and the village experienced little economic growth.

Originally, the main economic activities were grain cultivation in a three-field system and some vineyards.

In the 19th century this shifted to cattle and dairy farming and fruit cultivation.

Since 1963, Stadler Fahrzeuge AG produces their electric railway rolling stock.

[15] Bussnang is shaped by Stadler Rail, the sixth-largest railroad manufacturer in the world.

In addition to sales, Bussnang is also home to the competence center for the SMILE, FLIRT and GTW type series as well as the Tailor Made division (including railway and broad-gauge vehicles).
