Hi, I am busy planning an 00 scale layout utilising Hornby settrack and would like to get clarity on the gap required between two opposite Skaledale platforms with a double track in between. I am somewhat confused by various information provided. In the Hornby catalogue track section the centre to centre measurement of the rails is indicated at 68mm whilst the British Railways Modelling standards Bureau who have a very useful cross-section between platforms { Fig. 01} indicate 50mm centre to centre of track { dimension P }. Whilst I realise that the width of wagons and overhangs of locomotives vary this is a huge disparity in information and I would appreciate some guidance on the subject. My platforms will be on a straight section of parallel track. Thanks
