UP's M-10005 'City of Denver' of 1936 - morten1996 - 10-02-2013 Some Photos of scratchbuilding the A- and B-unit: Turning this and this via this into that and that Detailing the shell with batten & rivets will follow this autumn /winter Currently the aux-power/baggage car #11700 is under construction. Regards Norman Re: UP's M-10005 'City of Denver' of 1936 - e-paw - 10-02-2013 That's very cool . Can you go into some detail on how your drive works ,and the body construction please ? Re: UP's M-10005 'City of Denver' of 1936 - morten1996 - 10-02-2013 Hi e-paw, regarding your questions: 1) Power supply is by on-board batteries (two sets of three 12V-batteries in series). Either one very powerful 4QD-controller or two less powerful controllers (one for each truck) in a master-slave set-up will manage the four PM-motors (one on each axle) of the A-unit. The controllers are similar to those of golf-carts with forward/reverse and regenerative braking capability. Motors are connected via an idler to the axle (gear reduction app. 4:1). The (master-)controller will be connected to a control box (wired through the B-unit). The drive line it's not finished now, however, apart from being (much) more powerful as in my other locomotives, it's up to just the same. 2) Plain areas of the shell received a basic layer of fiber-board,on a steel-tube frame. The nose was shaped from styrofoam, the roof from expanded metal screen. All areas were covered with app. 1/4" glass-reinforced plastic. Finally the foam core of the nose was removed. A view into the shell (nose area) after removel of the foam-core More pix you'll find here in my projects' blog : http://large-scaledieselmodels.blogspot.de/search?updated-min=2012-01-01T00:00:00-08:00&updated-max=2013-01-01T00:00:00-08:00&max-results=17 Regards Norman Re: UP's M-10005 'City of Denver' of 1936 - Ralph - 10-02-2013 Absolutely amazing!!! Looks superb! Re: UP's M-10005 'City of Denver' of 1936 - Charlie B - 10-02-2013 That is one beautiful locomotive, a job very well done. Please keep us updated. I am in awe of your accomplishment. Charlie Re: UP's M-10005 'City of Denver' of 1936 - Tyson Rayles - 10-02-2013 Awesome!!!!!! What's the scale and gauge? Re: UP's M-10005 'City of Denver' of 1936 - morten1996 - 10-03-2013 Thanks for the nice comments! @Mike: Scale is between 1.6" and 1.7" to the foot (1/7.3 in 'metric' system)). It will be running on 7 1/4" gauge (gauge used in Europe and Eastern US). I know, scale is a bit too large (should rather have been between 1/8 and 1/7.8) but it fits to the wheel's diameter I'd on hand. Regards Norman Re: UP's M-10005 'City of Denver' of 1936 - modelsof1900 - 10-03-2013 Excellent modelling! Highest craftsmanship! Congratulation to your extraordinary models! And I love the Aero train! Norman, where can you run these locos and trains? Re: UP's M-10005 'City of Denver' of 1936 - morten1996 - 10-05-2013 Hello Bernhard, There are more than half a dozen live steam clubs in a distance up to 50 miles from here. No problem to run one's train there as a guest after asking permission & giving a small donation at the day's end. They usually welcome visiting trains to get some variation of their rolling stock which consists mainly more of narrow-gauge steamers with rolling sit-astride benches for public transport rather than real 'model trains'. But currently I prefer building trains rather than running them... However, photos taken on those tracks are much nicer than in front of my house on the pavement... But it is too much effort to take the models under construction to a club for a photo-session without actually being able to run them. Best regards Norman Re: UP's M-10005 'City of Denver' of 1936 - Puddlejumper - 10-05-2013 WOW. Amazing work! I would love to build a model that size, but I would most certainly go live steam and that would be much too time intensive and expensive! Re: UP's M-10005 'City of Denver' of 1936 - nkp_174 - 10-29-2013 (nothing but the sound of my jaw hitting the floor) Re: UP's M-10005 'City of Denver' of 1936 - morten1996 - 04-05-2014 Some further progress: A-unit's skirts were reaching too much downward (never trust schematic diagrams in books....) in comparison to prototype's photos - so here's the revised design. Additionally the trucks received all of the (virtual) brake equipment etc.: front window's shape was revised at the edges Shell and roof of the ride-on engineer's car (prototype's auxiliary power baggage) are basically finished - however, same problem with a skirt reaching too much downward...so another 'optimization loop' will follow Regards Norman Re: UP's M-10005 'City of Denver' of 1936 - morten1996 - 07-05-2014 Some progress on the A-unit - after sanding most of the details (steps, handrails, logos & herald, additional exhausts, battens) have been applied: Now similar treatment of the B-unit and then setting rivets, lots / thousands of rivets.... Regards Norman PS: (to estimate the dimensions of the unit: distance between sleepers is app. 8") Re: UP's M-10005 'City of Denver' of 1936 - morten1996 - 07-29-2014 Now with additional stirrups/ladders, several hatches and fuel glasses and the B-unit on the same level of details: Regards Norman Re: UP's M-10005 'City of Denver' of 1936 - Kev1340 - 08-12-2014 Incredible work Norman :o Cheers, Kev |
