We use Victron Energy Charger/ Invertors on our MK1 trains along with an appropriate battery pack in some cases the original BR type batteries. The Restaurant Car for the Wealden Pulman has a 12KW lithium battery pack which can power the kitchen equipment (we still use Gas for the actual cooking) refrigeration, POS, dishwasher etc. The stock is charged when it is parked up. We have shore supplies available for when the coaches are used statically away from Tenterden.This conservatism is what holds this country back! - Surely this is worth a go to see if it can attract more paying customers to the line. If nothing else it has got the railway some free publicity
I am more interested in how they are going to power the machines!
