Agreed.

However; let's not get stuck on price. If the construction is plastic/metal, considering the size of the market and the complexity of the model, the price is fair.

My compliments to Mr. Hass, be it for money or enjoyment, for undertaking this project. Excellent work! I'd like to see it a bit further along, but am interested. C'mon guys! A TT scale Big Boy!!! More enthusiasm is required.

I agree pricewise, but I'd think a quality 2-8-2 would be a heck of a lot more useful. I'm not sure I've ever seen a layout in any scale that wasn't completely overwhelmed by a Big Boy or a Challenger. Has Mr. Hass given any indication of the minimum radius this beasty will negociate?

I'll add my opinion to the thread. Would I buy one? No. It's to large an engine for the size of the layouts that are being built. Also I'm not up 100% on my European exchange. What would that cost me in dollars?

I have to agree with Tom. Why not a more useful steamer such as a 2-8-0, 2-6-0, 2-6-2, 4-6-2, 4-8-4 or any of the other smaller steamers. Why does it need to be a Big Boy that was only used out west on Sherman Hill or Tehachapi Loop? An engine like this would not fit my eastern theme. I'd be very interested in either a 2-8-0 or 2-8-2. I'd even settle for the small switchers.

CSD I think the price is fair if as I said it's a reference model. And if it is, I will plead, beg and, borrow and will come up with the $$$.

Let us see if he is open to suggestions.
It looks like the drive is arranged as a diesel. That is not correct and it would cause problems with the 2nd set of drivers and with the steam pipes between the 1st and 2nd set.
Either the minimum curve radius would be rather large or he would have to make the firebox narrower.
HP Products Big Boy has the frame of the first set of drives attached at the end - same as the real locomotive. Big Boy is a Mallet articulated design type.

(this is only a principle, I know that the number of wheels is different)


Then I would remove the flanges on the inner drivers (2nd, 3rd, 6th, 7th) if it is supposed to run through sharper curves.

Yeah, this. At like 2 large in Canadian I would fully expect this to stand up to any sort of scrutiny I or even more critical rivet-counters could throw at it.

Hi Big Boy fans,

I can't discuss why Ingolf Hass has chosen this model. After making such a proto type, there is no going back to the drawing board and make something else. Perhaps the next time if this is a success.

One small correction in the specs:
- the motor unit in the house is powering 2 * 8 wheels

The price is at this point an estimation.

I will ask what the minimum radius will be.

Ciao,
Rob

The drive is arranged similar as a diesel. I have seen it at the fair in Marienberg.
