I'm certain it not a Bogie, as much as I'd like it to be, thinking more along the lines of a 2-6-0 such as one of these. The cab door is open to the gangway unlike on a Bogie which is framed.
As to what number I have no clue but the details are similar to these two.

As for the prefered Passenger 2-8-0 mentioned above, the #60 seems to have been the clear favourite.
