Arry and Bert will most likely be clean.  Get out your weathering kits!

A basic start would be to watch this:

Watch all the parts and it will give you a good idea and a good start in knowledge on layouts.

That would be according to your DCC controller.  There are sites explaining how to set multi-train settings with helper and "bankers". 

I used to have the Prod. Express.   It had a feature for that.

Should give you a good idea how to install one for any engine.

The face is the size of TT#2's face.  it wouldnt be big enough.

There is a kit, but it is a brass kit that requires soldering.  Currently, there isn't a Norman model with a suitable face that will fit.

Well it is called two things.  All depends on where you are coming from. There is the North Western Railway, as mentioned in the Railway Series books, and there is the Sodor Railway, as said in the TV series.

It has been discontinued along with a few other rolling stock items in the Thomas range.

So when will we actually find out the real list for 2013 for new products? 

Here's to hoping for Oliver, Stepney, or a S7 engine!

Thank you!
