That would be Geelong Rd or Anakie Rd (the Horseshoe curve bridge?)

Dog Trap Gully Road, there used to be a half-mile post near here, 37.5
MP, I think.

I think this is about 63.8

I think Bank Box is 1650 metres?, therfore 65.5

The number makes it 71.3 from Flinders St (?), but don't remember the
Finders St-Spencer St distance... 1km?, call it 70.3

>Ballan 1018 (79.680km)

So, then we have:

place		distance		time		elapsed		speed	cumulative speed
		KM		CLOCK		DAYS(!)		km/hr
BM		51.12		9:49 AM			
HSB		56.45		9:54:00		0:05		64	
DTGR		60.00		9:58:00		0:04		53	
BBOX UP	63.8		10:03		0:05		46	
BBOX DN	65.5		10:05		0:02		51	
AUTO		70.3		10:10		0:05		58		55

Time in days because Excel does it that way, signif figures not
shgown, but they're there..

I figure the total mass was 477 tonnes/tons (R is 187?, 3BK, 2S, Z,
PCO?).

This very rough calculation (BM-Auto) gives a rail horsepower of about
2300, which would be a record for an R-class if true, almost up to a
38-class.  When I refine the figures, I bet the HP goes down!  But,
2300  more or less represents the increment expected on the basis of
oil-firing, Lempor exhaust and other "Wardaley" things.  Usual max. HP
of a "standard" R class was about 1700.
