CapEx vs OpEx

 

CapEX vs OpEX

CAPEX Model (Capital Expenditure):

• Buyer purchases the asset outright using capital funds
• Ownership immediately with buyer
• Buyer responsible for maintenance, consumables, and lifecycle management
• After warranty → Comprehensive Maintenance Contract (CMC) arranged separately
• Asset retained and disposed by buyer after useful life
• Expenditure = one-time (lump sum)

---

👉 Example: A Railway office buys 20 computers

• Full payment made at once
• Computers become Railway property
• After warranty → office arranges AMC/CMC (Annual/Comprehensive Maintenance Contract)
• Office purchases consumables (keyboard, mouse, parts, etc.)
• After 5–7 years → office disposes the computers

👉 Meaning: You own the asset and manage everything

—-------------------------------------------------------------------------------------------------

OPEX Model (Operational Expenditure):

• Seller provides the asset as a service (no upfront purchase)
• Ownership remains with seller
• Seller handles maintenance + consumables + performance
• After contract → asset taken back by seller
• Buyer does not handle disposal
• Expenditure = periodic / staggered payments

---

👉 Example: A Railway office hires 20 computers on contract

• No heavy upfront cost
• Monthly/quarterly rent paid
• Vendor provides maintenance + replacements + consumables
• After contract → vendor takes back computers

👉 Meaning: You just use the asset; vendor handles everything

🎯 Core Exam Difference (One Line)

👉 CAPEX = Buy & Own
👉 OPEX = Use & Pay 

👉 CAPEX = Buy laptop 💻
👉 OPEX = Rent laptop 💻

GTKM vs NTKM

 

GTKM vs NTKM

Railway Terminology

GTKM (Gross Tonne Kilometre) 🚆

Standard Definition: Total weight of a train (including locomotive, wagons/coaches and payload) moved over one kilometre

It is a measure of total transport effort of Indian Railways

👉 Simple Practical Example:

Total train weight = 1,000 tonnes and Distance = 100 km

GTKM = 1,000 × 100 = 1,00,000 tonne-km

👉 Meaning: Railways use fuel, track capacity, and manpower to move entire train weight, not just goods

NTKM (Net Tonne Kilometre) 📦

Definition: Weight of only the paying load (goods/passengers) carried over one kilometre. It is a measure of earning output

👉 Simple Practical Example:

Goods weight = 600 tonnes and Distance = 100 km

NTKM = 600 × 100 = 60,000 tonne-km

👉 Meaning: Revenue is generated only from payload, not from engine or empty wagons

Key Difference (Exam Ready) 🎯

GTKM → Total weight moved (Effort)

NTKM → Paying load moved (Earnings)

Better Real-Life Analogy 🛻

A delivery truck travels 100 km

Total truck weight (vehicle + goods) = GTKM

Only goods inside the truck = NTKM

👉 Fuel is consumed for full truck weight (GTKM)

👉 Income comes from goods delivered (NTKM)

One Line Memory Trick 🧠

GTKM = Gross = Full train 

NTKM = Net = Only earning load

Vertical Reservation Vs Horizontal Reservation

Reservations - Vertical Vs Horizontal

By Smt Sangeetha, Ch.OS/personnel/SCR

Vertical Reservations

Reservation for Scheduled Castes, Scheduled Tribes, Other Backward Classes and EWS is referred to as vertical reservation. It applies separately for each of the groups specified under the law. This is mentioned in Article 16(A) of the Indian Constitution.

Horizontal Reservations

It refers to the equal opportunity provided to other categories of beneficiaries such as women, individuals with disabilities and Ex Service men, cutting through the vertical categories. It comes under Article 15(3), 16(1) ,309 resp.of the Indian Constitution.

                                                    Difference between

Basis	Vertical Reservation	Horizontal Reservation
Constitutional Basis	Article 16(4) of Constitution of India	Articles 15(3), 16(1),309 of Constitution of India
Categories Covered	SC, ST, OBC, EWS	Women, PwD, Ex-servicemen, etc.
Nature	Social backwardness-based	Special provision / affirmative action
Competition for Open Seats	Allowed Candidates can compete in general merit	Not separately applicable
Merit Adjustment	Candidates selected on merit in open category are not counted against reserved quota	Candidates selected on merit are counted towards horizontal quota
Effect on Quota	Reserved quota remains intact even if candidates are selected on merit	No separate expansion of quota; adjusted within vertical categories
Application Method	Applied independently to each category	Applied within each vertical category
Filling Procedure	Direct allocation to categories	Two-step process: first fill vertical quota, then adjust horizontal quota
Example	SC/ST candidate selected on merit will not reduce SC/ST quota	SC woman selected on merit counts towards SC women quota
Key Principle	“Meritorious reserved candidate does not consume reserved quota”	“Meritorious candidate satisfies horizontal quota”
