I am in the process of taking my first adventure in trying to detail an engine of mine.  The items I am planning is adding fire cracker antenna, operating ditch lights & rotary beacon.  As I am looking at a drawing at http://www.sooline.org/publications/drawings/locomotives/SD60/SD60.jpg .  I see the items and placement I am looking to do.  But I am not sure of the item that is placed toward the very front of the roof before the antenna.  Can anyone help me with this item?  Thanks for the help as always!

I have recently received a Bachmann GP40 that I am repainting to match a short line that runs in my area.  This is a DC engine and I would like to convert it to DCC.  Has any done this?  More specifically does the motor need to be isolated?  From what I can see my first thought is yes but I would like to also hear from someone who has done it as well.  Thanks!

We have not run trains in some time and felt it would only inspire us
to move quicker on the layout if we started to run them again. So on
the freight yard leg (a section that worked previously) I connected
power to it and my Digitrax DCS100 shorted and shut down the system. I
have disconnected the rest of the layout from this area, checked for
something on the tracks and verified wiring under the layout. I can
only come up with that after ballasting and painting that a switch is
shorting. We are using Atlas snap switches and a Digitrax Super
Chief. Any ideas would be most helpful .. thanks!

I recently had gotten a Bachmann GP40 and I woul like to repaint it as the local shortline.  What are the suggestions for doing so?  I would imagine I do not want to just paint over the engine with the paint and decals that are currently on it.  Thanks!

I have a small river that I need to gap.  I have a Wye that curves over this river for about 10 inches.  Any suggestions on a bridge?  Thanks

I think one thing I would really like to see is a seperate DCC Board.  It becomes difficult to sort and sift through all the posts.  It is great that so many of use communicate through this media but wouldnt another filing cabinet for our DCC questions and comments be a good idea?
