 Buses for routes 37 , 47 and X47 between Edinburgh and Penicuik were branded as Penicuik City Link , with blue uppers and roofline , and the positions of the red and madder on the skirting transposed . In 2011 , one of these buses was repainted into madder and white , with no roof colour . However , the other vehicles in Penicuik City Link colours were repainted into the new madder and white livery with a turquoise mint coloured roof and the name Pen @-@ Y @-@ Cog . This is to celebrate the history of the area as Pen @-@ Y @-@ Cog is the original name for Penicuik . These buses were de @-@ branded in 2014 due to high fuel consumption of the B7TL 's used and the 37 / 47 / X37 is now worked by standards liveries Volvo B9TL 's .
