Hello,
I just discovered, with my great horror, that there's no such thing as Marklin C-track R3 bridge (curves).... Any suggestion on how to do them? |

I collect mainly DSB, DB and SBB but I'm quite... Open minded.
I'm quite a big collector of NOHAB lok :) |

How about combining straight bridges - see pic?  Would be prototypical, too... |

I have tried using straight bridges, but if they have handrails or high curbs, the longer passenger cars get caught up on the inside of the curve at each joint or rub the outside of the curve in the middle of the bridge. You need a really wide bridge to overcome this. I have the same issue with the long Jaegerndorfer Railjet coaches on an R2 bridge and had to remove the handrails.

Maybe you could make your own, depending on the type you want.
If it is a stone bridge then get a bridge and use silicon to make a mould of the side of the bridge [ use soap solution as a separator] . When the silicon is set , you can add epoxy resin to the mold say 2 mm thick. I have done that with tunnel entrances. I dropped different coloured grouts into the epoxy to get the colours and you get a very effective result. Once the epoxy is set, it can be shaped to the curve you want.
You could also do the same with polystyrene as has been demonstrated on the forum. [ Martin from Sweden and also Luis { Sparrow } ]

A German gent built a stone arch viaduct himself.  The body is made of plywood, the curves are also made of very thin plywood which he put in water to bend it into shape.  http://www.railroad24.de...nbahn/forum.php?id=14544Maerklin R3 = 515 mm / 30°. The supplier Luetke offers a 30° plate girder bridge for a 553,9 mm radius curve in H0 scale. Maybe adaptable via kitbashing?  http://www.luetke-modell...1648-1649-1898-1902.htmlI once built a single track curved stone arch bridge by carving arches into styrofoam and covering the result with random ashlar texture sheet from Scalescenes (www.scalescenes.com) printed on plain heavy paper.  Another time I used Peco LK-10 Plate Girder Bridge Sides (bent into shape after resting in warm water for several minutes) and 3 mm cardboard for constructing a double-track curved bridge.  https://www.peco-uk.com/...T_ID=3323&P_ID=17264 |
