Thanks for the help... I have usually only jump into this train thing during Christmas-time...so the assistance is appreciated... If I decide to go the LED route do I solder them in place of the incandescent bulbs???

I have a Suwanee River Big Hauler... It is several years old, we use it at xmas and the combine, which is the 9v type lights are inop.  How difficult is it to fix the lights... is there a schematic on this site??? Also  The battery door on my tender has broken, I see the part in the exploded view on the schematic guide on this website but cannot find it as an available part...
