I saw a hornby oo scale starter set on ebay and did some research and learned that oo can run on ho track but I couldnt find out how big the hornby pullman cars and castle class locos are compared to something like an ho amfleet 1 and I dont want anything to big on my layout so are the hornby ones about the size of an ho scale train or bigger??

Please help I want to model an amtrak phase ivb consist and want to use bachmann coaches. I could only find the bachmann phase v(actually phase ivb) cafe on ebay but dont know where to buy coaches also pleasedont give links where the coach is out of stock reply as soon as possible
