British Airways CitiExpress

[hazehoe]

Looking on the BA website i see that CityExpress is operating the RJ 100 ,Emb 145,Bae 146 and DHC 8 , are the ATP's gone ?,is it likely that they keep flying with 4 or 5 different "types"? Do they have all simulators in house or they train somewhere else?
And how much planes do they have?

Thanks
