From what I could see on the news report, the fire damaged the right hand side of the station and it's said that it destroyed both some trains and some track. Feasible as the storage tracks are inside the station too.
It's lucky that the main body of the ride is pretty far from the station area so in that respect the damage was pretty minimal really.
It's been said that the park hopes to reopen the Nash within a month - bring it on - I'll be there 
The Alice in Wonderland ride and Trauma Towers looked to be pretty badly damaged but as stated, the park intends to restore all three rides.
