Philosophically, what's the difference between using drawings to make something, and potentially using the same drawings and 'something someone made earlier' from them? I see reusing a 317/455 as just as authentic as extruding (or even machining) a huge lump of aluminium. But that's probably a debate for some other thread!
...or use the original equipment.
As I mentioned, a number of original Cl210 vehicles still exist and it would be good to reunite them. I'm not even especially concerned about the reuse and/or conversion of Cl317/Cl455 vehicles given their similarity. I'm certainly not expecting this project to include the construction of a completely new train.
We should not be distracting from the project by arguing about authenticity in this manner; the most important thing is to plug the gap while the opportunity is there.
I disagree, and I think it's important to be clear exactly what this project is going to produce at the end of it if any of us are going to pledge money. I've no doubt that we all have an idea what a Cl210 replica should be, and if this project is to succeed in it's aims then we should be confident that this is what will be realised. As it stands, there is precious little information about this except for the desire to recreate a Cl210 and the wish to raise the funds to buy a single Cl317 vehicle; something that I'd like to know is a realistic possibility given that these units are going to scrap with destruction orders on them.
To me this is a long way short of knowing where this project is going. I'd like to know that the project team have a realistic chance of securing the vehicles in spite of the current scrapping policy. I'd also like to know what they propose for the traction package, whether they have any leads on examples of the correct original equipment or will use a modern alternative. In short, I'd like to know how much of a real Cl210 this is likely to be or whether we're going to get something different out of this.
As I hinted above I'd not be terribly disappointed if at the end of the process we end up with a diesel-electric unit formed out of withdrawn Mk3 outer-suburban EMU vehicles in order to preserve vehicles of the type in operational condition, something along the lines of the Cl769. But I would be incredibly disappointed if I'd thought my money was going towards a Cl210 reconstruction.
As time is of the essence it is up to the project team to come up with a cogent plan and to communicate it clearly to those of us with an interest to be involved rather than for us to empty our spare change into a Just Giving fundraising page merely because we agree with the sentiment of the person setting it up in the hope that it will bring something to pass. We could also do with having some confidence in who BRCW Co actually are, what their track record in rail preservation is and what facilities they have available to them so that we can judge how likely they are to deliver what they promise, otherwise it's
caveat emptor.
