My guess would be that as GBRf are exhibiting examples of their operational fleet there, they would be used to haul the 4TC there. This will probably be very close to the start of the weekend, so the locos are unavailable for their normal duties for the shortest time possible.Is anyone aware of when the intended 4tc unit will be taken to East Grinstead as part of there Diesel gala event? Hoping to see it pass as it makes its way there
