Type TU1 and TU2
Some cars damaged during World War II were rebuilt with new car bodies and electro-pneumatic doors. These cars rebuilt between 1947 and 1953 were initially redesignated as Type B, but were later designated as Type TU1.[2] 100 cars underwent refurbishment from 1959 until 1961 and received stainless steel paneling and rebuilt car ends, and were designated as Type TU2.[2]
