High-Voltage Railway OHE layout CAD Drafting

I need an experienced CAD user to prepare electrical drawings for a high-voltage railway OHE installation and a few related works. My focus at this stage is a clear, buildable set of basic blueprints—plan views, single-line diagrams, and simple cable routing sketches—that accurately reflect the specifications I will provide.

Scope
• Produce electrical layouts and sections for overhead electrification (25 kV class)
• Generate single-line power distribution diagrams tied to those layouts
• Annotate conductor sizes, mast positions, and bonding points as per the template I share
• Deliver drawings in both DWG and RVT formats, layered and ready for future detailing

I will supply site survey data, reference standards, and sample sheets. Keep the model lightweight and well-organized so we can evolve it later into a detailed package if required.

Accuracy, logical layering, and adherence to railway electrical drafting norms are critical. If you have prior high-voltage or rail experience, please mention it and include one comparable sample in your bid.
