Assessment Criteria
Key criteria assessors look for in your portfolio
- Award credit for demonstrating a thorough risk assessment and safe isolation (mechanical/electrical) before any work, including verification from an authorised person.
- Evidence of correctly following the equipment manufacturer's maintenance schedule and recording all actions accurately on job cards or electronic records.
- Credit for identifying and reporting defects outside the planned schedule, clearly documenting the issue and action taken.
- Award marks for consistent use of appropriate personal protective equipment (PPE) and compliance with COSHH when handling cleaning agents or hazardous substances.
Assessment Guidance
Guidance for achieving higher grades
- 💡Narrate your actions during practical assessment to demonstrate your understanding of why each safety step is taken (e.g., 'I am verifying isolation because...').
- 💡Always cross-reference the maintenance schedule with the actual equipment serial number to ensure you are using the correct documentation.
- 💡Before finishing, review all records for completeness, ensuring any defects are logged with clear descriptions and signatures.
- 💡Practice waste segregation to ensure immediate compliance; examiners often observe disposal of rags, batteries, or cleaning solvents.
- 💡Always use correct technical terms like 'fishplate', 'tamping', and 'ballast' to show understanding.
- 💡In practical questions, structure your answer in chronological order and include safety steps first.
- 💡For calculations, show all working and include units in the final answer.
Common Mistakes
Common errors to avoid in your coursework
- Failing to confirm safe isolation with an authorised person before starting maintenance, leading to potential safety breaches.
- Over-tightening or under-tightening fastenings by not using a calibrated torque wrench according to manufacturer specifications.
- Incorrectly assuming that 'lifed' consumables don't need replacement if they appear functional, neglecting scheduled replacement intervals.
- Inadequate recording of sensory inspection findings, missing subtle signs like slight burning smell or discoloration.
- Misconception: Fishplates are only used to join rails of the same length. Correction: Fishplates join any two rail ends, regardless of length, and allow for expansion gaps.
- Misconception: Tamping and stoneblowing are the same process. Correction: Tamping compacts existing ballast, while stoneblowing injects new stones to lift the track; they are used for different maintenance needs.
- Misconception: PPE is optional if the work is quick. Correction: PPE must always be worn as per risk assessment; even short tasks can cause injury.

Step-by-Step Worked Solutions
Detailed solution breakdown for typical exam problems
Question: A rail is 18 m long at 10°C. The coefficient of linear expansion for steel is 12 × 10⁻⁶ /°C. Calculate the expansion gap needed if the maximum temperature is 40°C.
- 1.Step 1: Identify given values: original length L₀ = 18 m, temperature change ΔT = 40°C - 10°C = 30°C, coefficient α = 12 × 10⁻⁶ /°C.
- 2.Step 2: Use formula for linear expansion: ΔL = α × L₀ × ΔT.
- 3.Step 3: Calculate ΔL = 12 × 10⁻⁶ × 18 × 30 = 0.00648 m = 6.48 mm.
- 4.Step 4: The expansion gap should be at least 6.48 mm to allow for expansion.
Question: Describe the steps to replace a defective fishplate on a running line. (6 marks)
- 1.Step 1: Obtain a safe system of work (e.g., possession or lookout warning) and wear appropriate PPE.
- 2.Step 2: Remove the bolts from the defective fishplate using a wrench or impact driver.
- 3.Step 3: Remove the old fishplate and clean the rail ends with a wire brush.
- 4.Step 4: Position the new fishplate and insert bolts, ensuring correct alignment.
- 5.Step 5: Tighten bolts to the specified torque using a torque wrench.
- 6.Step 6: Check the joint gap and alignment, then remove tools and confirm the area is safe.
