I just tried to find an instructional manual for my hellgate bridge, took me a while to guess which sub-page it'd be on, a process of elimination it was, and after finally finding the right area the database didn't even have the manual listed (6-32999). I ended up e-mailing customer service to see if they may can find one for me.
It's a sign of the times that many companies, large and small, have poorly designed websites; it appears many designers don't seem to have a clue about running a business or attracting customers. Poor websites are a capital destroyer as my business-minded friends like to say. I suspect that for Lionel, and MTH, others, potential customers who have a passing and/or nostalgic interest in electric trains will browse to the Lionel site with a strong impulse to find and buy something, only to give up and leave after a minute of two of weeding through all that fluff. Us "train people" spend the time going through sites, but we are the exception to the normal customer I think.
One common trait that successful companies have integrated into there web designs is simplicity and ease of operation. Display your products, price, and how/where to order, and customer service. Everything else is glitter.
