MT files

Apologies in advance here for being a bit of a numpty, but I've a couple of questions here regarding the MT files kindly hosted on TSSH as I'm trying to create some activities based 100% on that said stock
1) Regarding the electric locos, there appears to be 2 'versions' of the same engine, one of which containing the suffix 'P', eg, MT Class 90 001 ICS, and MT Class 90 001P ICS. What is the difference, please? (is it something to do with the Pantograph??)
and
2) Is there sufficient stock there to put together a class 90 IC Swallow rake including standard, first and dining / buffet cars?

Really embarrassed to have to be asking this!
Cheers

Hi Terry,

The P is for the engines set up for Push-Pull opperations so that they could run with the Mk3 DVT.

As for coaches, so far there is the Mk3 loco hauled sets. I have been messing around with the MT Mk1s trying to get a few of the missing types done but that is still a way off yet (so far there is only the pre-existing BR Blue and Grey Livery). I haven't gone near the Mk2s yet.

Regards,
Justin

Thanks Justin,
Shows, never to old to learn!
I'm going to plod on with what's already there. Might turn out to be atypical, but ho-hum.
Cheers
