Yes Sir,I've spotted numerous times.Sometimes when catching my Onward Train for Bangalore I need to spend as long as 16-18 Hrs @ HWH.So I'm pretty sure about these RSA & you can see the pics uploaded also.RSA b/w 12338/12341 is not possible as it'll not have min 7 Hrs rest,which it needs at the Base Station.All these rakes belongs to ER & their base is HWH.
