I recently recovered an HO layout that was in storage for 25 years.  Much to my surprise I can get one locomotive out of 3 to work.  The other two only show the light when power is applied but will not run.  Is there any place I can have these locomotives looked at for possible repair.  The layout also has 6 switches with Atlas remote controlers that don't work with the electric controler.  Any thoughts on getting them to operate.
