Unusual Locomotive Proposals

So I was scrolling through facebook just now and when I was on one of the pages which I usually visit, I found, this...….https://www.facebook.com/photo?fbid=231 ... 4480405301 (NJT Dual Mode Proposal)

Apparently the, ur-, proposal shown here was an actual dual mode proposal for NJT back in the 200s.

With this in mind, does anyone have any other "unusual" locomotive concept art to be posted?

Here are some more examples from the same page:

Edit: Sorry if the links go to the same photo album three times. I had separate pictures posted when I first pasted the links.
The ones I was speaking of was the proposal for the Burlington E5, the Amfleet-based Diesel locomotive, and the Double sided electric F40 for NdeM.

Here's another example. Unusual proposed liveries can count too.

Perhaps this might qualify for inclusion here, a 16-axle, single-frame electric locomotive proposal from Westinghouse:





It was actually part of a suite of proposals included in AIEE paper 48-54 “Electric Locomotives with Identical Basic Components”, by W.A. Brecht and Charles Kerr, Jr, both of Westinghouse, and presented 1948 January.


All variants shown used the same B-truck with non-lifting lateral motion.


The three-truck variant was the basis for the PRR “experimentals”, albeit single- rather than double-ended. As originally ordered, AC motors were specified, with a change to Ignitron rectifiers and DC motors made before building. Apparently the PRR had reservations about the three-truck, B-B-B layout, hence the inclusion of the C-C variant. Westinghouse had anyway hedged its bets, designing and patenting a trimount C-truck with non-lifting lateral motion, this at a time before anyone had actually built a swing-bolster C-truck, and when such was regarded as a somewhat difficult proposition. Possibly this Westinghouse truck was originally specified for the C-C experimental, but evidently events on the way to the forum led to the GSC single-swing bolster trimount C-truck being used. GSC patented both this and a double-swing bolster version at about the same time, following its initial patenting of its version of the UK LMS Ivatt-Fox design with non-load carrying low-profile bolster. So the Westinghouse C-truck remained a proposal.

The four-truck running gear was used under the Westinghouse GTEL prototype.
