The British Rail Class 320 is an alternating current (AC) electric multiple-unit (EMU) passenger train found on the Strathclyde rail network in Central Scotland. They are mainly used on the North Clyde Line and the Argyle Line, but they can also be seen on Glasgow Central to Lanark and Cathcart Circle services. The Class 320 I believe would add just that bit more variety than just all Class 314's on the Cathcart Circle route in my opinion and would be a decently fun train to operate. I hope you consider this suggestion of mine one day , thanks in advance
Good idea in principle but as Matt P rightly stated last night before any considerations are given to expanding rolling stock DTG will monitor sales of Cathcart circle to ensure there is viability and the demand that warrants or nessescitates doing extra rolling stock for Cathcart
