Greetings.  This is my first post, although I've been reading along for some time.

We have been slowly acquiring some of the HO scale Thomas and Friends engines, and through random chance, it seems as if we have only gotten the short ones (Thomas, Percy, James, Toby, and Mavis).  It is our intention to build a shed with a roundhouse for our small layout.  As our local hobby shops never seem to have them on the shelves, my question is- what are the dimensions (length, especially) of Thomas' longer friends (Emily, Gordon, Henry)?  I have briefly searched the web for engine specifications, with no luck.

Thank you for your time.
