There is no "R160". There are R160A-1s, R160A-2s, and R160Bs.
R160A-1s were made by Alstom. They are in four car sets. They are going to the Eastern Divison.
R160A-2s were made by Alstom. They are in five car sets. Nobody knows where they're going.
R160Bs were made by Kawasaki. They are in five car sets. Nobody knows where they're going. A few sets have Siemens propulsion.
All the R160 cars look identical.
