I am continuing to make a new layout set in Glasgow in an inner-surburban area, a contemporary ficional station inspired by Polkshields East. It will have mrk 3 and mrk 1 catenary masts and will have foliage and a background of tenements which I may paint on the backdrop. I am just working out the clearances on the slightly curved platforms using the simple but effective masking tape and a pencil method. I attached a pencil to the centre of my longest bogie on one side pointing downwards. I then ran the vehicle on the inside curve, with the pencil on the inside and made a line on the baseboard which gave me a good idea of the inner clearance curve. I've marked the outside curve too in a similar way, I now just have to be careful when laying the track to get a nice smooth line.
