Dear Wanda: You are not alone in the care of large objects that are, by nature, forced to sit outside and weather in the elements. The Association of Railway Museums (ARM) publishes a superb document called "Recommended Practices" which is often hailed by the AAM as a great example of a museum group finding and promoting its own professional standards. A board member from ARM is near you in Vancouver. Contact Don Evans, President, West Coast Railway Association, Box 2790 Stn Main Vancouver, B.C. V6B 3X2 Phone: (604) 524-1011. Best wishes!
