I always travel in roomette with a 8"clip on fan and a small porcelain heater. The Fan is used 90% of the time in all seasons. I only used the heater in the winter months to warm up the room for after getting out of the shower. And before all you voltage experts jump in, it doesnt blow the breakers it the same wattage as a hair dryer....even less on low and medium. A few years ago on a sold out train the heating was out on the A bedroom and the couple in it couldn't take the cold. I ask the SA if we could trade my working heat roomette for their non working heat bedroom. My little porcelain heater kept that bedroom right at 73 degrees the whole trip. The twin size electric throws from Walmart work well also and fit nicely. If you have to sink was a clothing item the heater is also great for drying that,.
