i had downloaded over 200 trains add-on,i will only use one type of train in one route,when i try to add more train to service the route,is to difficult to find the train,is it possible to add a filter in purchase list,just like the 「vehicle list」

This was discussed some time ago, and denied, because this feature would be helpful only for a few pak-sets.(http://archive.forum.simutrans.com/topic/04374.0/index.html should be the topic in the forum archive, but I can't connect to the webserver).
To copy an existing train, it has to be in the depot; when viewing it there, just press the copy button. Vehicle setup and schedule of the new train will be the same.

My apologies about the forum archive being down, there's more information about why in this thread.

Thanks.
