zephyr1934 Posted April 10, 2013 Posted April 10, 2013 Yeah it is a pretty insane prototype, but the system was used with success for contractor railways during the Victorian era. Ah good point, there are plenty of pictures all the way up to the 1920's where a temporary narrow gauge railroad on panel track was used on large construction sites. For quick track one rail is easier than two. Quote
Hrw-Amen Posted April 10, 2013 Posted April 10, 2013 Looks good, since seeing these I have been looking at pictures of these strange little engines online. There seems to be a few in India and they are running through sort of shanty type areas. Perhaps a hog-pog of ramshakle huts is called for at one point on your layout? Quote
Locomotive Annie Posted April 10, 2013 Author Posted April 10, 2013 Well the Kotanga Valley Posthole Mining Co. might pass for a collection of ramshackle huts Hrw-Amen Inspector Grumpimann is rendered speechless by the sight of the posthole co's new coach. Quote

Locomotive Annie Posted April 11, 2013 Author Posted April 11, 2013 Hey! I was just about to post my first carraige. The worker wagon. Great minds must think alike ES; - do you have any more pictures of it? I thought my loco looked lonely sitting all by itself on the track I've laid so far so I built the green passenger coach to keep it company. The posthole mining co only owns the one coach anyway so it was an easy choice. At the moment it's sitting on a pair of wheels as I only had two spare ones of the type of wheel I'm using, but I've ordered more and when they arrive the coach will be converted to riding on two two wheel bogies as well as two balance wheels. I'll most probably make the coach about four studs longer as well. One item of rolling stock at least has to be articulated just to prove it can be done One thing I've found though with the wheels I'm using, they can't be spaced at more than seven studs between axle centres or else they flange bind on 12volt curved rails. Putting the coach on bogies should improve its general running whereas the loco seems to be quite happy with its driving wheels adjusted to 7 stud centres (remember the centre driving wheel isn't there and is only represented by an axle and the outside cranks).

Locomotive Annie Posted April 11, 2013 Author Posted April 11, 2013 (edited) 'I did it with this', says Olivia. After a lot of fiddling and adjusting I've got my Ewings monorail loco to go around 12volt curved rails without flange binding. Yes I know the rubber tyre is a dreadful cheat, but it works fine with the two flanged wheels acting to guide the loco around the curve while the rubber tyre on the driving axle can act like a wide blind driving wheel as well as supporting the rear of the locomotive. Next job on the list is to start in on building the goods wagons for carrying the refined and finished postholes down from the mine. Fortunately I've got a copy of the original Ewings patent drawings to guide me. Edited April 11, 2013 by Locomotive Annie Quote
Locomotive Annie Posted April 11, 2013 Author Posted April 11, 2013 (edited) Update: A further refinement. If you take one of these wheels........ http://www.bricklink...Item.asp?P=3482 and fit three 12volt traction tyres on it one on top of the other you will end up with a very much more tidy blind driving wheel. How you actually get three traction tyres onto this wheel is entirely over to you, but I will warn you, - it will involve swearing Edited April 11, 2013 by Locomotive Annie Quote
bricks n bolts Posted April 11, 2013 Posted April 11, 2013 Fantastic stuff Annie and ES, you're both totally insane....a great use for blue track too, of which I may add I have plenty... Quote
Man with a hat Posted April 13, 2013 Posted April 13, 2013 I agree. These are great creations. Amazing and very creative. Quote
LEGO Train 12 Volts Posted April 14, 2013 Posted April 14, 2013 Beautiful creation Locomotive Annie! Totally cool and absolutely original! Quote
Electricsteam Posted April 14, 2013 Posted April 14, 2013 Look at the gears does this move on its own? Quote
Locomotive Annie Posted April 15, 2013 Author Posted April 15, 2013 Look at the gears does this move on its own? Yes it's motorised with a 4.5volt motor ES Quote
mfeldt Posted June 14, 2015 Posted June 14, 2015 There's a modern day variant in operation in form of the Padova Tram: http://www.metrotram.it/index.php?vmcity=PADOVA&vmsys=tgo&ind=0&num=6〈=eng Maybe also something for Lego? Quote
