Re: Bombardier 185 vs 188
This site has a lot of information about the various loks and types: https://www.railcolor.net/index.php?nav=1404957&lang=1
The 185 AC1 was derived from the DB class 145 and was intended to operate on either 15 or 25kv. The 185s were produced in both versions with only 2 pantographs and in versions with 4 pantographs for multiple systems. The 2 pantograph versions were mainly seen in Germany and Austria only.
The 185s with 4 pantographs could be used in Germany, Austria, Switzerland, and parts of Luxembourg and France depending on whether the lok was homologated for that country and equipped with the necessary safety systems.
