request for externals

Hi all, i am looking for externals of either the class 317 or 319, the liveries dont really matter but Midland or thameslink will do, I have searched but drawn a blank, if anyone can remember either class at any time being produced or even partly produced i would be grateful for the link..regards

On the sandymill line I believe there is a 317 object and the Southern Blighton to Treston Park route has a class 319 too..

Thanks for that Kieran, didnt find either object on those routes, unless they were on an earlier version, i`ll keep looking, perhaps it`ll have to be another new object to add to the list.....regards
