Thanks for your comments. I have previously used the other 3 you have posted as well as a Class 170 in order to make more of them. I don't post mine up to the Internet currently as the new ones I have made are very detailed (An example of this is the bogies on the MK3s above) I have now made a Class 67, Class 90, Class 153, Class 155, Class 158, Class 168, Class 170 and Class 377.
Here's a Class 377 Pantograph and Bogie detail - little bit burry but you get the idea -

At the moment, I am unsure about what I am going to do with them.
Thanks,
