probedb Posted July 6, 2020 Share Posted July 6, 2020 Is it possible to permanently attach track to the Hornby girder bridge?Reason is we need to attach track to stop it raising up slightly at each end. We're following a Hornby trackplan but the track isn't sitting as it should so it raising itself up at one end of the bridge. There looks to be holds that something could attach to but there isn't anything supplied? Link to comment Share on other sites More sharing options...
Chrissaf Posted July 6, 2020 Share Posted July 6, 2020 Glue?.It sounds as if you might have some fairly aggressive gradients leading up to and down from the bridge with particularly coarse transitions from flat to slope..If this is so, then I predict you will experience grief in the form of derailments and trains not being able to run up the slopes..Unless you have the space to implement very gentle slopes ie a minimum 8 foot straight run to rise 3 inches (longer if the rise includes curves), then they really are best avoided. The track plan you are working from, may very well be an old one designed when locomotives were heavier, had more powerful motors and might also have had 'Magnahesion' for use on old steel rails (modern rails are non-magnetic Nickle Silver). These old plans that include slopes and gradients in relatively small layout footprints really do not suit the more modern light weight / low power locomotive rolling stock.

96RAF Posted July 6, 2020 Share Posted July 6, 2020 Whilst not a Hornby girder bridge I just ran two lengths of semi-flex track across my 600mm long twin track bridge securing only to the baseboards eiher side of the chasm. Glue or double sided tape could have been used on the bridge bed./media/tinymce_upload/82f8ff71e0819c2811f51635a187e919.JPG Link to comment Share on other sites More sharing options...
morairamike Posted July 6, 2020 Share Posted July 6, 2020 /media/tinymce_upload/841617623fe7feecd1ed1a19c8d2f83a.jpgIn my case the track was laid in pre-ballasted foam underlay and the foam glued to the bridge base. The end plates are drilled and screws go through the holes into the base boards at each end of the bridges. Small cool springs are fitted around the screws under the end plates. This way the screws can be adjusted to give a smooth transition between the bridge rails and the board rails. Link to comment Share on other sites More sharing options...
Jimbo1707820979 Posted July 7, 2020 Share Posted July 7, 2020 Excellent idea about the coil springs and screws. I'll be using it ! Thanks, Mike. Link to comment Share on other sites More sharing options...
