The Analog Incident Story Traincar Diorama: Building a Shoebox-Size Outage World You Can Rearrange by Hand
How a simple shoebox-sized traincar diorama can become a powerful, low-tech simulation environment for rehearsing complex outage scenarios and improving organizational resilience.
The Analog Incident Story Traincar Diorama: Building a Shoebox-Size Outage World You Can Rearrange by Hand
When we talk about outages—data center failures, regional power loss, broken networks—we usually picture dashboards, graphs, and scrolling logs. But for many people who need to respond in a crisis—facilities, HR, communications, leadership—those abstract screens don’t make the situation feel concrete.
Enter the analog incident story traincar diorama: a shoebox-sized, physical model that turns complex outage scenarios into something you can literally pick up, rearrange, and reason about with your hands.
This isn’t just arts and crafts for engineers. It’s a deliberately low-tech simulation environment you can use to:
- Model complex systems in a tangible way
- Explore how failures propagate
- Rehearse cross-functional outage responses
- Run branching “what-if” storylines
- Build muscle memory for rare, high-impact events
Why Build a Shoebox-Size Outage World?
Most organizations already run tabletop exercises: people sit around a room, read an incident scenario, and talk through their response. This is useful—but heavily dependent on imagination and shared mental models, which are often misaligned.
A physical diorama changes the game by:
- Making abstractions visible: Power, network, facilities, and people become objects in space.
- Revealing hidden dependencies: You can see that your “redundant network” still passes through one physical telecom room.
- Encouraging participation: Non-technical stakeholders can see and touch the scenario, not just listen to jargon.
- Lowering the stakes: It’s easier to experiment and question assumptions when you’re literally moving little pieces around.
Think of it as a model railroad for operational resilience: small, safe, but structurally faithful to the real world.
What Goes Into the Traincar Diorama?
You don’t need to be a hobbyist modeler. A simple shoebox or traincar-sized box and some basic craft materials are enough.
Step 1: Define the “World” You’re Modeling
Pick a scope that’s big enough to be interesting, but small enough to be understandable. For example:
- A single data center or office building
- A regional cluster of offices
- A logistics hub with IT, power, and personnel
Your diorama represents that world in miniature.
Step 2: Map Key Reliability Components
Borrowing from reliability engineering and SRE thinking, identify the major parts of the system you care about:
- Power: Utility feed, backup generators, UPS units, critical vs. non-critical loads.
- Network: ISP links, routers, switches, fiber paths, WAN vs. LAN.
- Facilities: Server rooms, cooling, elevators, access control, safety systems.
- People: On-site staff, remote teams, leadership, vendors, emergency responders.
In the diorama, each of these becomes a physical object:
- Blocks or tokens for buildings and rooms
- Colored string or tape for power and network lines
- Small icons or game pieces for roles and teams
- Sticky flags for “this is critical” or “this is shared infrastructure”
The key is relative structure, not cosmetic accuracy.
Step 3: Show the Dependencies
Outages are about dependencies under stress. Use the model to display them:
- A power line (red string) to the main telecom room
- Network cables (blue string) that all pass through a single MDF
- Arrows or labels that show “HR depends on VPN, which depends on this router”
When someone asks, “What happens if this room floods?” you can simply remove or cover it and see what else breaks.
Using the Diorama as a Mini Simulation Environment
Once built, the diorama becomes a low-tech simulation lab. You can:
- Prototype new redundancy plans
- Visualize architectural changes
- Test response runbooks with real humans
Simulating an Outage
Pick a scenario, then represent it physically:
- Place a red marker on the failed power feed.
- Cover the primary network path with a card labeled “Fiber cut – ETA 6 hours.”
- Remove the “on-site staff” tokens and replace them with “remote-only” tokens.
Now ask the group:
- What immediately loses function?
- Who notices first? Who doesn’t notice at all?
- What’s degraded vs. completely offline?
As people answer, move the pieces. This creates a shared visual narrative of the outage.
Rapid Prototyping of Configurations
One of the strengths of a physical model is how cheaply you can change it:
- “What if we add a second ISP that enters on the opposite side of the building?”
- “What if the generator only powers half the floors?”
- “What if the backup office shares the same substation?”
Build those into the diorama and rerun the scenario. You’ll quickly see which changes meaningfully improve resilience and which are just cosmetic.
Branching Storylines: Choices Under Pressure
Real incidents are not linear. People make decisions under uncertainty that shape the outcome.
Design branching storylines into your exercises, with clear decision points:
The power from the utility fails. The utility promises an update in 30 minutes, but doesn’t provide an ETA. Do you:
A. Wait for more information from the utility
B. Immediately initiate backup plans and shift to remote work
In the diorama, explore both branches:
-
Branch A (Wait):
- Time passes. Move a clock token forward.
- Add a card: “Utility update delayed; new ETA unknown.”
- Show accumulating impact: more services degraded, staff idle, customers frustrated.
-
Branch B (Act):
- Move people tokens to “remote” locations.
- Enable backup power only for core services.
- Add a card: “Increased load on VPN – capacity at 85%.”
Discuss with the group:
- Which path minimized impact?
- Which created second-order problems (e.g., overloaded VPN, miscommunication)?
- What would you do differently next time?
Over multiple runs, you can refine decision trees and embed them into your formal runbooks.
Cross-Functional Rehearsal, Not Just for Engineers
High-impact outages touch far more than IT. They affect:
- Ops / SRE / IT: Systems, data, applications
- Facilities: Power, cooling, physical access
- HR: Staff safety, attendance, policies
- Communications: Customer updates, internal messaging
- Leadership: Risk tradeoffs, business continuity decisions
The diorama gives all these groups a shared stage.
Example Exercise Flow
-
Set the Scene:
- “It’s 10:30am on a Tuesday. A regional power outage hits. This is our primary office and data room.”
-
Introduce the First Failure:
- Remove utility power from the model.
- Facilities explains what happens in the building.
-
Add Cascading Effects:
- Network gear loses power in a certain room.
- VPN access degrades; remote work slows.
-
Prompt Decisions:
- Leadership chooses between closing the office vs. partial operations.
- Comms drafts messaging based on what they can see on the board.
-
Debrief:
- What worked? What surprised people?
- Did everyone share the same mental model of what was affected?
By repeating this with variations, teams build shared understanding and muscle memory without waiting for a real disaster.
Designing Repeatable, Game-Like Scenarios
Training, gaming, and simulation research all emphasize repetition and variation as keys to skill-building.
Treat your diorama sessions like a game system:
- Scenario cards: Pre-written prompts like “Elevator outage during evacuation,” “Regional ISP outage,” “Fire alarm during maintenance window.”
- Difficulty levels: Start with a single failure; later, introduce compound failures (e.g., power failure + staff illness + supplier delay).
- Resettable state: After each run, quickly return the diorama to baseline.
- Metrics: Time-to-decision, clarity of communication, number of unrecognized dependencies.
Over time, you’ll build a library of repeatable drills that improve readiness the same way pilots and emergency responders use simulators.
Why Low-Tech Beats Another Dashboard (Sometimes)
This isn’t about replacing digital tools. It’s about complementing them.
A hands-on model:
- Slows people down just enough to think clearly.
- Makes it easy to ask “dumb” questions—often the most important ones.
- Surfaces hidden assumptions in architecture diagrams and runbooks.
- Encourages collaboration and richer discussion.
When everyone is looking at the same small box, pointing at the same string of “network cable,” arguments about terminology drop away. You’re building a shared mental model of resilience that persists long after the exercise ends.
Getting Started Tomorrow
You don’t need a budget approval cycle to try this. Start small:
- Grab a shoebox, sticky notes, colored string, and a handful of tokens.
- Sketch your primary site layout in the box.
- Add power and network paths with string.
- Place team roles as tokens.
- Run one simple outage: “The main power feed is cut for 4 hours.”
- Ask: What breaks? Who acts? How do we recover?
Document what you learned, then iterate on the model.
Conclusion: A Tiny World for Big Resilience Questions
In an era of complex, distributed systems, it’s tempting to believe that only advanced software can help us understand outages. But sometimes, a shoebox-sized analog world is the best way to:
- Make complexity visible and tangible
- Experiment with failure and recovery safely
- Align diverse stakeholders around the same reality
- Build the habits and instincts you’ll need when things really go wrong
The analog incident story traincar diorama doesn’t replace your monitoring, your dashboards, or your sophisticated simulations. It gives you something simpler and strangely powerful: a little world you can rearrange by hand, where you can practice failing—and recovering—before it truly counts.
