I know about the modified EWI ABt and EWII BDt.
I am looking for more specific information on the coaches rebuilt from former Dt/DZt EWI/EWII.
I know that BLS was operating at least one in the original configuration (green/red front).
Which ones were scrapped and which ones were converted and what were the coach numbers of the BDt conversions?
I think that the BDt Zugkraft Aargau was one of these.
