More than a few. Mars light, big number boards, car body filters replacing windows--I'm surprised it still has its coupler cover.
I believe the UP unit is an E6, they only owned one E3 and both their E3 and E6s received such modifications.
I like the Santa Fe E1s. That smooth, uncluttered front end with the steep slope was really gorgeous. Along with the B&O EAs, some of the finest Es to polish the rails. Not that they dethrone Alco PAs...

Like a lot of military locomotives of that era, it was adjustable gauge, like the MRS-1. The only model designation I can find for 4700N is RS4-TC-NG.
Count me in too, when you get that time machine running! That 4700N is a gem. I'm sure the photographer wasn't pleased then, but now it's a rarity.
I serendipitously stumbled on a photo of a very similar unit in the Second Diesel Spotter's Guide. Davenport built 18 of them back in the 1950s. Sixteen were standard gauge, numbered in the 1200s. One, 4000, was adjustable from standard up to 66-inch gauge, and last but not least, 4700N was adjustable to narrow gauge. Whitcomb also built some, occasionally credited as Baldwin. Case closed!

Love the traction photos. Did some research to find that the Denver Tramway had a gauge of 3' 6". The image above looks to show a dual gauge arrangement at this location.
Traction companies often augmented their income delivering freight from online businesses to the local yards of interstate railroads. A few survive to this day continuing that service. I would guess that's the reason for the dual gauge, and they stuck to narrow gauge trolleys because they never converted the whole line to dual gauge/standard gauge, just the industrial neighborhood. I'd be interested to hear from someone who knows if that guess is right.
The dual gauge wasn't for freight purposes, but rather two different companies. This section of line was the connection between the standard gauge Denver & Intermountain interurban and the narrow gauge Denver Tramway. The D&IM was a subsidiary of Denver Tramway, however. The line from 12th & Federal was dual gauge into downtown Denver at the Central/Interurban Loop (14th to 15th and Arapahoe to Curtis) so the passenger cars of the Denver & Intermountain could enter Denver. In the earliest days of the D&IM, solid blocks of coal gondolas from the mines around Louisville and Boulder would travel this line to get into Denver for delivery to customers (mainly domestic homes and businesses). There was (and still is), little industry along that particular route. The coal movements were the exception, however, it was strictly for passenger service.
