Several jewelers and banks provide certified and pure silver coins. Silver coins can also be bought online but only buy it from verified vendors to minimize the risks and ensure you always receive a purity certificate with the item.
The Rail Coach Factory in Kapurthala, established in 1985, has been instrumental in bringing this innovation to life. Series production of these coaches began shortly after initial trials, with the coaches being gradually integrated into various express trains across the Indian Railways network. The deployment of these coaches represents a significant step toward modernizing the passenger experience while maintaining affordability.
The 3E coach stands out with its innovative design elements that maximize passenger comfort while increasing capacity. These coaches incorporate numerous technological advancements and passenger-centric features that distinguish them from traditional AC coaches.
One of the most notable features of the 3E coach is its increased passenger capacity. While a standard Third AC (3A) coach accommodates 72 passengers, the 3E coach can carry 83 passengers – an increase of 11 berths. This enhancement was achieved by relocating the high-voltage electric switchgear from inside the coach to underneath the frame, creating additional space for berths.
The berth configuration in 3E coaches differs from traditional 3A coaches. Each compartment in a 3E coach contains 9 berths – 6 facing forward and 3 in the opposite direction – compared to the 8 berths in 3A compartments (6 main berths plus 2 side berths).
The 3E coach features numerous improvements designed to enhance passenger comfort:
Individual AC vents for each berth, allowing personalized climate control
Increased headroom for middle and upper berths, reducing the cramped feeling often associated with these positions
Ergonomically improved ladder design for easier access to middle and upper berths
Foldable snack tables in both longitudinal and transverse bays
Wider toilet doors and entrance doors specifically designed to be accessible for passengers with disabilities
The 3E coaches are equipped with modern amenities that enhance the travel experience:
Individual reading lamps for each berth, allowing passengers to read without disturbing others
USB charging points and standard electrical sockets at each berth for charging electronic devices
Fold-out water bottle holders and dedicated spaces for storing mobile phones and magazines
Luminescent aisle markers and illuminated berth indicators with integrated night lights
Passenger information systems and public address systems for important announcements
Safety has been a priority in the design of 3E coaches, with several features specifically addressing passenger security:
Improved fire safety measures complying with the world benchmark standard EN45545-2 HL3 for materials
CCTV cameras and fire alarms installed throughout the coach
Luminescent floor markers that glow in the dark to guide passengers in low-light conditions
Understanding the differences between 3E (Third AC Economy) and 3A (regular Third AC) coaches helps passengers make informed choices based on their preferences and budget.
While both coach types offer air-conditioned travel, they differ in several physical aspects:
3E coaches have 83 berths compared to 72 berths in 3A coaches
3E coaches have a narrower passage due to the additional berths
3E features green strips on the floor that glow in darkness, while 3A typically has blue flooring
3E has more modern foldable water bottle holders, which may not be present in all 3A coaches
3E upper berths have less headroom for sitting compared to 3A upper berths
3E coaches have stylish ladders for accessing upper berths, while 3A coaches typically have standard black ladders
One of the most significant advantages of the 3E class is its price point:
The fare for 3E coaches is approximately 6-8% lower than 3A coaches
This pricing strategy positions 3E as an intermediate option between regular 3A and non-AC sleeper class
The cost reduction makes air-conditioned travel accessible to more passengers without significantly compromising on comfort
Both 3E and 3A coaches offer air conditioning, but several amenities differ:
All berths in 3E coaches have individual reading lights, which may not be available in all 3A coaches
3E coaches have USB charging ports at each berth, which might be limited in older 3A coaches
3E washrooms feature modern foot-operated taps and have a more contemporary design compared to standard 3A washrooms
3E coaches have sliding doors, contributing to a more modern appearance and functionality
The 3E coach caters to a specific segment of railway travelers who seek a balance between comfort and affordability.
The 3E coach offers a compelling value proposition for passengers:
It provides essentially the same comfort level as 2A and 3A classes but at a lower price point
The air-conditioned environment ensures a pleasant journey regardless of outside weather conditions
Despite having more berths, the coach maintains a comfortable environment through smart design choices
The reduced fare makes it an attractive option for budget-conscious travelers who still want AC travel
The design of 3E coaches demonstrates Indian Railways' commitment to inclusivity:
Wider toilet and entrance doors make the coach more accessible for passengers with disabilities
The ergonomic design of ladders and berths makes travel easier for senior citizens
The increased number of berths makes AC travel accessible to more passengers, democratizing comfort
As Indian Railways continues to modernize its fleet, the 3E coach represents an important step toward balancing affordability with passenger comfort.
With the initial plan to manufacture 248 coaches across two fiscal years, Indian Railways has demonstrated a significant commitment to expanding the availability of 3E coaches. As of 2025, these coaches have been gradually integrated into more train services across the country, making the benefits of affordable AC travel available to a wider segment of the population.
The introduction of 3E coaches marks a new era in Indian railway travel:
It represents a shift toward more economical yet comfortable travel options
The innovations in these coaches may influence the design of future coach classes
By making AC travel more accessible, these coaches help to improve the overall passenger experience across the railway network
The 3E coach in Indian Railways represents a significant innovation in railway travel, successfully balancing affordability with comfort. By incorporating modern amenities, enhanced safety features, and improved accessibility, all while maintaining a price point below traditional Third AC coaches, the Third AC Economy class fulfills an important need in the market.
As Indian Railways continues to deploy these coaches across its vast network, more passengers will have the opportunity to experience air-conditioned travel without straining their budgets. The 3E coach exemplifies Indian Railways' commitment to evolving with passenger needs while making quality travel experiences accessible to all segments of society. This new coach class truly represents the next generation of railway travel in India – one that prioritizes both passenger comfort and economic accessibility.
