I am working on detailing some cars (BB+) whose sides contrast with their ends and/or roofs.

Is there somewhere I can learn which cars had which?  

I can tell you that this is a topic on which Google does a great deal better on recall than on relevance.  

And what is used on black boxcar doors, e.g., New Haven, paint or cement?

thanks for your help.

This is a 60' Intermountain wood deck flatcar with a Herpa Minitanks Oshkosh truck. I removed and added some decals on the flatcar to match the prototype car. I then weathered the car and used Alkem Scale Models etched brass chains to tie the truck down. Before you say the chains should be crossed, look at prototype pictures. I used drive truck pulling oversize and heavy. We always crossed at least one set of chains. The military must do things a little different. All of the pictures I found of these, none of them had the chains crossed.

I have acquired some diecast steam locos and tenders that I have not been able to identify. Can anyone tell me who manufactured these tenders with what looks like a doghouse on the back? 

I have an Atlas RS1 with ESU Lok.  I have CV3 and 4 set to a momentum of 200 each.  This morning when I fired her up, those settings were lost.  Now, I can't do anything.  It just sits and idles.  I go into CV8 and set a value to 8 for a factory reset and nothing happens.  I put in 3 on my NCE and that doesn't work.  I tried with the previous engine number programmed in (#200) and that doesn't work.  I'm not sure what to do now since I can't factory reset and start over.  I'm going out for a run.
