Abstract: Battery packs according to some embodiments of the present technology may include a first longitudinal beam and a second longitudinal beam. The battery packs may include a plurality of cell blocks disposed between the first longitudinal beam and the second longitudinal beam. The plurality of cell blocks may include first and second cell blocks each characterized by a first side surface proximate the first longitudinal beam, a second side surface, a third side surface proximate the second longitudinal beam, and a fourth side surface. The battery packs may include a first interface material thermally coupling the first side surface of the first cell block with the first longitudinal beam. The battery packs may also include a second interface material thermally coupling the third side surface of the second cell block with the second longitudinal beam.

Abstract: A railway car side panel assembly with upright support posts forming the side walls of the car wherein painted or galvanized panels are protected from rusting by plastic inserts positioned between the corners of the panels and metal brackets on the posts to prevent vibration-abrasion of the galvanizing or paint and of the corners to rust, the plastic inserts being of flexible plastic material and formed as envelopes pocketing the corners and fitting into the complementary brackets, the envelopes each having a side wall with a retainer bottom snapped over flange edges of the panel to hold the envelope from falling off during assembly with the brackets.
