If you want to ride in a car at night, get together with some of your friends and charter a car. The museum will operate charters at almost any time of day or night. You can have your choice of most of the operating cars. Call (707) 374-2978 extension 114.

Museums must operate as a business, like it or not. Today, unlike the past, railfans and enthusiasts make up less than 10% of the paying visitors. I doubt night operation would get enough visitors even to pay the power bill.
