Life-Cycle Cost Analysis: A StarPath Rail road Material Supply Approach

At StarPath, we’ve developed a comprehensive Life-Cycle Cost (LCC) analysis approach tailored specifically for railroad fasteners. This method allows us to provide our clients with a clear picture of the total cost of ownership over the entire lifespan of the fastening system.

Railroad fastener cost analysis: Our LCC Formula

We use the following formula to calculate the Life-Cycle Cost:

LCC = IC + ∑[(MCt + RCt) / (1 + r)^t] + DC

Where:

• LCC = Life-Cycle Cost
• IC = Initial Cost (purchase + installation)
• MCt = Maintenance Cost in year t
• RCt = Replacement Cost in year t
• r = Discount rate (typically 3-5% for railroad projects)
• t = Year of expense
• DC = Disposal Cost

Real-World Application

Let’s apply this formula to a hypothetical 100-mile track over a 30-year period, comparing two fastener types:

1. Cut Spikes
2. Elastic Fasteners

Scenario Parameters:

• Discount Rate: 3%
• Traffic: Moderate to heavy

Cut Spikes:

• Initial Cost (IC): $1,000,000 ($10,000 per mile)
• Annual Maintenance (MC): $300,000 ($3,000 per mile)
• Replacement (RC): Every 7 years, $1,200,000
• Disposal Cost (DC): $50,000 (estimated for entire lifecycle)

Elastic Fasteners:

• Initial Cost (IC): $5,000,000 ($50,000 per mile)
• Annual Maintenance (MC): $100,000 ($1,000 per mile)
• Replacement (RC): Not required within 30 years
• Disposal Cost (DC): $100,000 (estimated for entire lifecycle)

Results

Using a financial calculator or spreadsheet to apply our LCC formula:

• Cut Spikes LCC ≈ $15,200,000
• Elastic Fasteners LCC ≈ $9,800,000

Despite the higher initial cost, elastic fasteners result in a lower LCC over the 30-year period, primarily due to reduced maintenance needs and longer lifespan.

Interpretation

This analysis demonstrates that:
