Oh, and time wise… Abadan were active in 1975 through to 1978 … Not sure why they packed in. Metrans was started in 1979 then changed to Satrans in early '81 with a bit of creative accounting and re registering of vehicles etc 
. It all finished later that year.
Strangely Abadan are never mentioned on the M/E thread.
Cheers now. Balders .
