"Will I get bed bugs on a sleeper car when I'm on the Empire Builder?" a reader recently asked. I understand the concern: I get a bedroom on the City of New Orleans train each year for a Thanksgiving trip to visit family. I enjoy watching the country roll by, but I'm always afraid I'll start itching.

After sleeping on Amtrak trains about 10 times now -- to and from, including a trip to Montana -- I can report that bed bugs have never been part of the unofficial welcoming committee. Small comfort, I know.

"Just like a hotel, at either end of the route or whenever a bedroom turns over, we change all the linens and vacuum and wipe down the compartment," said Amtrak spokesman Marc Magliari. Hmmm. That's even smaller comfort since several years ago a bed bug problem began plaguing hotels.

In a world of buggy uncertainty, there are measures you can take to protect yourself -- on a train or in a hotel room.

Search the room, particularly the seams of the seating-turned-bed. Bed bugs are annoyingly tiny, but look for dark specks (the bug's droppings), skin sheddings or the bugs themselves. Because Amtrak seats are a dark blue, run a white piece of paper along the seams to see if anything pops up.

If it does, well, look for other accommodations, even opting for a seat in a distant car. Bed bugs may be small, but they can move from bedroom to bedroom at up to 14 inches in 5 minutes. Consider wrapping your luggage in plastic. The bugs won't be able to hitch a ride on the slick protection. Once at home, throw your clothes into the dryer for 15 minutes. Heat will kill the bugs and eggs.
