How much would it cost to build a full size Peckett 040 loco?

Hi
Just wondering how much it would cost to build a full size standard guage working replica of the 040 Peckett steam locomotive?
I'm interested as I've seen how huge working replica locos like the Tornado have been build from scratch and would be good if smaller locos could be built by small scale engineering companies as a supply to small heritage railways theme parks, museums etc.

Thanks

I think a lot depends. As a one-off you're not going to get much change from £250,000 I should think - might even cost more.

If however, you have multiple orders, you can get some economies of scale and reduce that.

A lot would also depend on the degree of authenticity required, even Tornado contains a number of compromises between the original design and the needs of todays railway. Materials and skills have changed a lot, sometimes for the better.
Modern grades of steel and welding techniques rather than riveting permit of a higher boiler pressure than decades ago.
Roller bearings reduce both frictional losses and maintenance requirements.

If main line running is contemplated then both air brakes and an electrical system are requirements.

A useful addition to a new steam loco would be electric heaters in the waterways of the boiler, to be plugged in to a shore supply overnight. Starting with the boiler hot, but not under steam pressure would save a lot of coal and time and trouble in the morning.
IIRC, one of the narrow gauge heritage lines has done exactly this.

So yes, a new build broadly similar to an old design is entirely possible but an exact replica is probably not viable, and would certainly not be allowed on the national network.

As others post, costs would depend on the numbers built. 4 would not cost 4 times the price of one.

The UK got to 280 psi at least with riveted locomotive boilers so why would you want to go higher, especially on an industrial? As for an exact replica not being allowed on the national network, many industrial locomotives - mostly colliery based - in the past were registered to run on the national network so it is conceivable that grandfather rights could be claimed if a design was recreated. Not that I can see what use you'd get out of an industrial on the 21st century main line network.

Any particular reason for wanting a Peckett? As opposed to a Kerr Stuart, Hunslet, Barclay, Kitson or any of the dozens of other builders.
