what is it?

The Pioneer III railcar was a short/medium-distance coach designed and built by the Budd Company in 1956 with an emphasis on weight savings. A single prototype was built, but declines in rail passenger traffic resulted in a lack of orders so Budd re-designed the concept as an electric multiple unit (EMU). Six of the EMU coach design were purchased by the Pennsylvania Railroad with the intention of using them as a high-speed self-contained coach that could be used for long-distance commuter or short-distance intercity travel in the Northeast U.S. The 6 production Pioneer III units were the first all-stainless-steel-bodied EMU railcar built in North America and, at 90,000 pounds (41,000 kg), the lightest.
