How much bigger is the K27

I have a Bachmann Consolidation and I'm relaying track through the soon to be tunnel. How much bigger is the K27 than the Consolidation for clearance purposes on R2 curves?
 
Paul,
The K-27 will not run on r2 curves, minimum 8ft diameter, ideally you will want 10ft diameter for large 1:20.3 locos like this.

It IS big especially if you have the version with a snowplough. It will run on R3 curves and points but mine does NOT like LGB points. It copes fine with Peco and Piko but beware of wiring problems with Piko. Easily solved but a nuisance.
I will check mine tomorrow if nobody posts before that with sizes.
 
Here is the difference....

And, compared to another of Bachmann's G scale locos! :rolf:

Fascinating shot

The K27 is a standard gauge loco regauged by the D&RGW to 3 ft.

The mining moul has a dubious parentage, but although it appears in the Baldwin catalogue as a 3 footer, I'm sure that I've seen a photo of a similar outline loco from a 2 ft gauge railway

That would explain the difference in overall size

Not at all the k-27 was the first Mikado (2-8-2) loco designed speifically for 3 foot gauge and is quite small when compared with later D&RGW, White Pass and other 3' gauge locos. The K-36 and K37 locos are about a 1/3 bigger than the K-27.

I hadn't realised that - but yes, you're right the K27s were built as 3 footers, but ran over dual gauge track.

Clearly the D&RGW narrow gauge track beds had monster clearances. :-:-
 
The Rio Grande had to upgrade their lines several times to cope with each generation of larger N.G. locos. The first locos were very small 2-4-0s which could of run on many 2' lines. Only the large locos only ran on the busier lines and the reason that there were still C-16 locos running when the 3' gauge lines were closed that there were still some lines that were never upgraded to run the big locos and these small locos were the largest that the tracks could cope with.

The duel gauge tracks were only in the goods yards and maintenance facilities and on a few tracks for a short period whilst they were being regauged to standard gauge. You can find photos of some k-27s with dual height couplers and switching standard gauge wagons as in later years they were the yard switchers.

There were at least 2 batches of K-27s ordered from Baldwin and the Bachmann locos represent the later or rebuilt earlier versions. I wish that Bachmann had made one of the first batch in original condition as they had vertical compound cylinders and slope back tenders.
 
The K-36/37 were originally standard gauge locomotives that were 'regauged' for the 3 foot narrow gauge. When we say 'regauged', in fact very little of the original donor standard gauge locomotives remained on the narrow gauge derivative. The Rio Grande also used 'idler' flatcars to shunt their dual gauge trackage. Their idler flats had offset couplers to handle both narrow and standard gauge rolling stock.

If you think that the K-27 is big, then the K-36/37 are HUGE. If you wish to see dual gauge action, then Barry boggs is well known to scratch build both standard and narrow gauge in 1/22.5 scale. Link to site.

It is indeed unfortunate that just before the downturn of both LGB and LGBoA, Barry had sent masters to LGBoA to make accurate length Rio Grande passenger rolling stock with a view to production.

Nearly correct but the K-36 were new built Baldwin 3' gauge locos and the K-37s were rebuilt from 0-8-0 standard gauge switchers into close copies of the Baldwin K-36 design. The K-37s reused the boiler, cylinders and some body and tender parts from the donor locos but on a new outside frame chassis copied from the K-36.
 
The K-27's arrived in 1903 in one batch , #450-464. They were built as Vauclain Componds with slope back tenders. They were converted to simple slide valve engines after problems with the compound system and frame cracking from plowing snow. The final rebuild was to piston valve engines , although not all of the engines were converted over. The K-28's arrived in 1923 and halted complete conversion of the remaining K-27's . 2 of the K-27's remain in existence .

K-37s were originally C-41s, 41000lbs TE Connies.
Although lighter than K-36s they were much harder on the tracks and were not allowed

Back on topic, thanks for the replies, especially the pictures. I guess that a K27, should one ever come to the Long Dream Line, will be banned from the curved tunnel.
