The handrail can travel at different speeds but it is not supposed to. The American National Standards Institute code ANSI A17.1 requires that the speed of the handrail shall not change when 444.8 newtons are applied against the direction of motion. To meet this requirement, the handrails are sometimes adjusted to move slightly faster than the step.
Escalators that are installed under the ANSI A17.1-1990 code require that a handrail-speed monitoring device be installed. If the speed of the handrail changes by more than 15 per cent, all power is removed from the motor drive and the brakes are applied.

Two reasons that interlink.
1) An escalator makes you lean backwards. This is optically compensated by a slightly faster moving handrail.
2) If you hold on to a handrail that went the same speed you would be pulled backward at the bends. This could cause you to fall backwards.
Both are in place to prevent you from falling.

Because the "stairs" are moving just a bit slower than the rail....though personally, I try to never touch the rail anymore, saw a documentary on dateline or one of those news story shows that a ton of germs pass on those things daily and they hardly ever get sanitized...euuu! If I DO touch them, I get out my purell right after!

I've noticed this on most escalators and never thought much about it.
My guess is that the designers are trying to disorientate people and make them fall down.

The rail moves a little faster than the steps do.

Actually, it's human nature to hold the handrailahead of you and lean back.
