Any KSF or R151 trains on CGL is good tbh (knowing that KHI are really getting worse on EWL after the disruption one month ago), the KHI fleet can continue to operate on mainlines until their retirement and since they only operate during the weekday peak hours mostly now, they have been spread out on both lines while majority of them on NSL now. Currently, 38 KHI trains in service (excluding 065/066, 125/126 and 127/128 while the other 8 trains are not seen for now)
