I added the two Weaver cars shown below recently. They are, believe it or not, the first two Weaver products I own. I was ordering some 'Streets stuff from a big Internet retailer and since I was paying shipping anyway, I checked their "Newly Arrivals" page, where I could not resist the combination of Union Pacific cars and Navaho trucks. I have no idea if these are actually newly released products or long-time products newly arrived at the retailer.
I didn't know what to expect from Weaver, either. These two are a bit underwhelming - not bad, just not impressive: I have some recent Lionel and MTH 50' cars similar to these but both have a tad more detail. These cars also have noticeably more friction in their trucks (even after gently lubing them in case they were dry) than the others, particularly the Lionel, which will just run away down even the slightest slope if left by themselves. I'm not really disappointed - I wanted and love the Navaho trailers - the lack of detail, etc., won't even be apparent when they are moving, so they're fine. Not sure I will order any more though, Lionel and MTh seem to have spoiled me with their latest stuff . . .
