Claim Text:
1. An underfloor transformer comprising: a layered transformer core having two axial end regions and a plurality of limbs which each extend horizontally in a parallel arrangement and are stacked on top of each other; at least one electrical winding through which the transformer core extends along a limb axis, the at least one electrical winding comprising at least one cooling duct for guiding a coolant along the at least one electrical winding; and securing devices each respectively provided in a corresponding one of each of the two axial end regions of the transformer core, wherein the securing devices are configured to interact mechanically with the transformer core, and are configured for tensile force stressing such that the underfloor transformer can be carried suspended from the securing devices given an approximately horizontally oriented limb axis, and the securing devices having at least one suspension device configured to support the entire weight of the suspended underfloor transformer below the at least one suspension device, wherein the underfloor transformer is configured to supply energy to a rail vehicle, and wherein the transformer core is a unitary structure which extends undivided along the limb axis between the securing devices.
