I have just received my new little Era 1 engine from Hornby.

 

It will join the Patentee class ('Adler' but the name will change for my English mid-C19th layout), 'Lion', 'Tiger', and (soon) an inexcusably heavily-weathered 'Rocket'. 

Lion and the Patentee will pull my passenger trains, Tiger will be fast goods, the blacked-up Rocket will haul coal and 'Locomotive No.1' will probably have a train of bulk freight such as bricks.

The layout is not started yet, and I've not even prepared the room to take the layout, but the locomotives are best acquired now before Hornby's entire stock of Era 1 locos all ends up on eBay with a 50% mark-up.
