note - The vast bulk of my massive Web presence (over 485 pages) had been hosted by AT&T's WorldNet service since 30 May 1996; they dropped WorldNet effective 31 Mar 2010 and I have been scrambling to transfer everything.  Everything's saved but all the links have to be changed, mostly by hand.  See my sbiii.com Transfer Page for any updates on this tedious process.

HORSESHOE CURVE

Continuation Page 3

NOTE:  HTML limited my pages to 30kB!  Thus, I was forced to add separate pages to fit the lengthy stories of the prototype and HO (1:87.1) Berlinerwerke; the Berlinerwerke-Z (Z-Scale - 1:220) story is on its own page.

INDEX

[APOLOGIA - I can't possibly keep track of all the interconnected linking on the Horseshoe Curve and Berlinerwerke-HO pages so I'm just posting the latter and reposting the former without 100% link correlation at first; hopefully I'll catch up with the links "one of these days".]

On the main Horseshoe Curve page:

Prototype Horseshoe Curve Story
Berlinerwerke (HO) Saga

On the Continuation Page 1:

Dimensions of the Horseshoe Curve - with HO (1:87.1) Scale Equivalents -
    a mile-by-mile and even foot-by-foot guide to the Curve.

On the Continuation Page 2:

UPDATE of the BERLINERWERKE (HO) Saga.

On this page, Continuation Page 3:

Dimensions of the Horseshoe Curve in HO (1:87.1), N (1:160), and Z (1:220) Scales-

On the Continuation Page 4:

Satellite Photo of the Horseshoe Curve, with description of features.

On the other RR pages:

S. Berliner, III's Railroad Page
S. Berliner, III's Pennsylvania Railroad Page
    with THE SOUTH PENN RR.
S. Berliner, III's Model Railroad Page
S. Berliner, III's Model Railroad Continuation Page
S. Berliner, III's Z-Scale (1:220) Model Railroad Page,

The BERLINERWERKE (HO) Story, the story of the HO Berlinerwerke pike.
The full prototype story will appear shortly.
The Z-scale Berlinerwerke-Z Saga is on a separate page.

Visit the courtesy and official home pages listed on the other pages (out of room here).

Dimensions of the Horseshoe Curve - with HO (1:87.1) Scale Equivalents -

    a mile-by-mile and even foot-by-foot guide to the Curve,
has been moved to Continuation Page 1.

The BERLINERWERKE (HO) Story, the story of the HO Berlinerwerke pike.
The full prototype story will appear shortly.
The Z-scale Berlinerwerke-Z Saga is on a separate page.

The table on Continuation Page 1 shows prototype and equivalent HO scale (1:87.1) dimensions; what follows is a conversion table which also lists N (1:160) and Z (1:220) scales.  For other scales, use the Scale Conversion Table on my Z Scale. page, although, except perhaps for S (1:64) or TT (1:128) there's not much likelihood anyone will model the full Horseshoe Curve in any larger scale.  Of course, Pennsy actually did model it once at a scale of exactly 12" = 1'!

Consider that Tiny Trains ½-Z scale (1:440) is exactly half of Z; the nominal radius of the curve would only be about 45", or less than 8' across from outer track to outer track with room for embankments.  In the even tinier 1:900 scale, that would be only 22"R or under 4' across!

Tabulation of Prototype Horseshoe Curve Dimensions
with HO, N, and Z Scale Equivalents.

NOTE:  The HO scale dimensions which follow were calculated with a scale factor of 87.1,
NOT with the more exact 87.08571428571-- (25.4÷3.5×12)!
