Re: South Africa...4-8-4's ???? *LINK*

No browning points.
The answer is the 15CA 4-8-2 built by Alco.
The 16E is a poppet-valve Pacific(4-6-2).
I actually saw the 858 operate from De Aar to Kimberly in 1977. They had been working on restoring it that year, and when we were there some kid fireman jumped off a 4-8-4 while stopped at a siding in Witput, and came running over to us(3 photographers), to chat. He was from Dayton, Ohio of all things. He mentioned the engine was to run in 2 days on "The Rhodesian Mail" a named passenger train that was 3 days a week in each direction. So, a chase ensued of that train which left De Aar before dawn, and didn't get light until about Orange River. I have some film and slides of this engine(858) from that run. Train was late due to the engine being broken in!!! Can't recall the driver diameter but since the 25NC was 60 inch, these were likely 70 inch. I know they were fast on those 3 foot rails during their regular service. Longer trains and newer 4-8-4's relegated them to retirement for the most part. I think some of the last pacifics were the 16DA(not sure), in commuter service around East London(early 70's??).
We got a lot of neat stuff on the 1977 South Africa Trip, but all my stuff is silent super 8 movies. The next year in the US I went to sound.

There is a shot of 1977 "Orange Express" on my website doing 60 miles per hour...look in "Greg's Gallery" on the right side of my home page.
