The roof and exhaust are now soldered in place.

Before rolling the roof to shape I annealed it by holding it over a gas flame (cooker) until it turned straw coloured then rolled it using a couple of round pieces of metal (the handle of a scraper and a piece of 5mm bar) using a copy of the Yellow Pages as a soft pad.

Then the roof was taped in place before being tacked using a small amount of solder in two places;

Once I was happy with the positioning, which took two attempts, I soldered the roof on from the inside. I use a small 1mm tip on my Antex which helps in these situations.

A pic from the rear for a change;

The exhaust pipe itself is 1mm diameter thin wall tube, from Squires, and the bracket is scrap etch, bent to shape, tinned, and attached using my RSU;

All soldering again done with 188 degree.

Comparing the loco to an Airfix figure shows that cab steps might be a good idea;

The wagon is a Roco U tub.
