BART’s 1960’s Rohr-cars were ahead of their time. Their superior power/weight ratio saves energy and accelerates trains quickly. By contrast, it appears their 21st-century “fleet of the future” will be weighed down with FRA-style collision posts.
The new design features smooth and flush surfaces. It also includes strong vertical posts built into the face of the cab to provide enhanced protection to people on board in the event of a collision.
Collision posts are expensive and unnecessary. Every extra dollar spent on them takes away money from actual safety improvements. Undoubtedly, this is the result of the 2009 Washington Metro collision. Federal regulators made a huge deal out of the lack of collision posts, even though the cause of that accident was a flaky train control system.
