## Essex learners usually start here

An eight-year-old in Wivenhoe who draws train layouts, a ten-year-old in Rayleigh who loves logic puzzles, a Year 10 in Brentwood heading for computer science, and a shift planner in Grays who wants to automate the rota. Four courses, and every one begins with a free lesson.

## Fourteen councils and 1,860,208 people from Tilbury to Harwich

Nomis supplies the 2021 Census head count for each council. For towns we use the ONS built-up areas, and we re-added the census output areas inside Essex ourselves to see which towns cross the county line.

| Council | Usual residents | Main towns |
| --- | --- | --- |
| Colchester | 192,715 | Colchester, Tiptree, Wivenhoe, West Mersea |
| Basildon | 187,571 | Basildon, Billericay, Wickford |
| Chelmsford | 181,523 | Chelmsford, South Woodham Ferrers, Galleywood, Danbury |
| Southend-on-Sea | 180,686 | Southend-on-Sea, Leigh-on-Sea, Shoeburyness |
| Thurrock | 176,001 | Grays, Stanford-le-Hope, Tilbury, South Ockendon |
| Braintree | 155,268 | Braintree, Witham, Halstead, Great Notley |
| Tendring | 148,291 | Clacton-on-Sea, Harwich, Brightlingsea, Walton-on-the-Naze |

Essex and Kent are close to the same size: our sum for the fourteen Essex councils is 1,860,208 and for the thirteen Kent councils 1,855,844. Like Kent, Essex has no dominant centre. Its largest built-up area, Southend-on-Sea, is shared between three councils: Southend itself, Castle Point and Rochford. Colchester's built-up area reaches into Tendring. And the county runs from the edge of London at Loughton and Chigwell to a North Sea port at Harwich, which is a long way to go for an evening class.

| Town | Usual residents | Town | Usual residents |
| --- | --- | --- | --- |
| Southend-on-Sea | 182,305 | South Ockendon | 22,440 |
| Colchester | 130,245 | Harwich | 20,215 |

Fifteen more Essex built-up areas have between five and eight thousand residents, from Great Notley and Wivenhoe to West Mersea, Walton-on-the-Naze, Great Wakering, Ashingdon, Galleywood, Danbury, Kirby Cross, Purfleet-on-Thames, East Tilbury, Hullbridge, Takeley and Little Canfield, Ingatestone and Jaywick. Every row we print agrees with our own count to within rounding except Harlow, which has about 430 residents on the Hertfordshire side of the line.

### School calendars in Essex

When we asked Essex County Council's website for its term dates on 26 September 2026 it declined to serve the page, so rather than copy dates from somewhere else we print none. Three councils and many academy trusts set dates here, and lesson breaks are arranged family by family. The county's selective tests have their own maths pages, for [Essex](/11-plus-maths-tuition-essex) and [Southend](/11-plus-maths-tuition-southend); this page gives no advice on schools.

The Essex project

## How many trains does the pier timetable need?

Four facts from the pier's own site, a little arithmetic, and a model that is honest about what it leaves out.

Start with the run. 1.33 miles at 8 miles an hour takes 9.98 minutes; at 10 miles an hour it takes 7.98. So a train leaving the shore on the hour reaches the Pier Head somewhere between 8 and 10 minutes past, which leaves it 5 to 7 minutes before the published quarter-past departure back. It reaches the shore again between 23 and 25 past, and waits 5 to 7 minutes for the half-hour departure. One train, going back and forth, can work the whole published timetable. We are not saying how many trains the pier actually uses; we are saying what the arithmetic requires.

| A train every | At 10 mph | At 8 mph | What changes |
| --- | --- | --- | --- |
| 30 minutes (as published) | 1 train | 1 train | Nothing: one train and slack at both ends |
| 15 minutes | 2 trains | 2 trains | Trains now meet on the pier and must pass |
| 10 minutes | 2 trains | 3 trains | The slower speed alone costs a whole extra train |

The last row is the one that surprises people. The difference between 8 and 10 miles an hour looks small, but at a ten-minute headway it decides whether the service needs two trains or three, because the round trip at 8 miles an hour is just over twenty minutes once each end has its turnaround. Fleet size jumps in whole trains, so a small change in speed can cost a large change in equipment. Every bus company, airline and delivery firm meets this staircase.

Now the single track. With two trains, one leaving each end at the same moment, they meet after 4.43 minutes. If both run at the same speed they meet exactly in the middle of the pier, which is where a passing place would sit. But if one runs at 10 miles an hour and the other at 8, the meeting point moves 119 metres from the middle towards the slower train's end. A passing place cannot move, so the faster train arrives first and waits, about a minute. Delay on a single track is not caused only by breakdowns; it comes from two trains that are each running perfectly well at slightly different speeds.

### Ages 10 to 13

Convert miles and miles an hour into minutes in Python, then print a timetable for one train and check it matches the published times.

### Ages 13 to 16

Write the fleet-size function, test it at many headways and speeds, and draw the staircase where one more train is needed.

### Ages 16 and up

Simulate two trains with random small speed changes on one track with one passing place, and measure how waiting builds up over a day.

### What the model leaves out

The pier's site says trains slow to 5 miles an hour through the points, and our simple model ignores that slowing. It also ignores loading time variations, weather and anything about how the railway is actually operated. The timetable and speeds are the pier's published figures; the fleet sizes, meeting points and waits are our own arithmetic, offered as a teaching model and not as a description of the real service.

Why the pier

## A railway along a pier, in the words of the people who run it

The pier and railway are run by Southend-on-Sea City Council; these facts are from its pier website.

| Topic | What the pier site says |
| --- | --- |
| Length | The longest pleasure pier in the world, stretching for 1.33 miles into the Thames estuary. |
| Timetable | Trains from the shore on the hour and half hour, from 10:30am, and from the Pier Head at quarter past and quarter to. |
| Speed | 8 to 10 miles an hour, dropping to 5 miles an hour through the points. |
| The trains | The current trains went into service in 2021. |
| History | A single-track electric railway began running in 1890; visitor numbers peaked at 5.75 million in 1949 to 1950. |

A railway on a pier is a gift for teaching because it is small enough to hold in your head and real enough to have published numbers. There is one track, two ends, one timetable and a known speed. Every principle of scheduling that applies to a national rail network applies here, without the thousands of complications. A learner who can reason about the pier railway properly can reason about any shared resource: a single lane of road, a shared printer, or two programs writing to the same file.

This page is independent: Modern Age Coders is not linked to Southend Pier, Southend-on-Sea City Council or Essex County Council in any way. Speeds, length and times come from the pier; the modelling and fleet arithmetic, mistakes included, belong to us.

## An AI can write a timetable in seconds. Can it tell you why the ten-minute service needs a third train?

Sometimes, if you ask exactly the right question. Knowing that question is the skill.

Ask an assistant to produce a timetable for a pier railway every ten minutes and it will cheerfully lay out departures. What it will not reliably do is notice that the timetable is impossible with two trains at the slower speed, because nothing in the request mentioned the fleet, and a list of times looks equally plausible whether or not the trains exist to run it.

An Essex student who has built the fleet-size function knows to ask how many trains, how long each round trip, and where they pass. Those questions turn a neat-looking output into a plan that works. The same habit catches the same mistake in every AI-generated schedule, rota or project plan: it may be tidy and still demand resources nobody has.

So an Essex teenager should learn to program in 2026 not to compete with machines at writing lists, but to be able to tell a workable plan from a tidy impossible one. The longer argument is in [why teenagers should still learn to code in 2026](/blog/is-coding-worth-learning-2026).

Getting started

## Harwich to Tilbury, and nobody drives anywhere

Essex is wide and its roads are slow at the times children finish school. Online lessons ignore both.

### Lessons wherever you are

A bedroom in Canvey Island, a kitchen in Saffron Walden, a desk in Loughton. The screen is shared and the learner does the work.

### The language of English schools

Key Stage 2 and 3, GCSE choices and A levels are named as Essex schools name them, in English.

### Start with a free lesson

A complete lesson of real work and a straightforward recommendation. Card details are never requested.

### Learners at one stage

Groups of five to ten who have reached the same point, gathered widely, so the lesson is pitched right for all of them.

### Breaks around your school

Two lessons a week is typical, and holidays are fitted to your own school's dates, which in Essex can vary by council and school type.

### Times stated in UK time

Our teachers are in India, ahead of the UK by four and a half hours in summer and five and a half in winter, and every lesson is booked in UK time.

Why groups are built by level in Essex

Fifty-five towns and no single centre mean that in any one town, few learners are at exactly the same stage. Grouping by level lets a Jaywick learner and an Epping learner work together.

Fees

## Fees in Essex

One price list for every Essex town, and for every country outside India.

First class**USD 0**

A full lesson with real work, finished with a recommended level and course.

Group tuition**USD 100**

Roughly eight lessons a month, with five to ten learners at the same level.

Private tuition**USD 150**

Roughly eight lessons a month, one teacher and one learner.

Every fee is quoted in US dollars, which is how we bill families in all countries apart from India; we do not keep prices in pounds. The first payment comes only after the free lesson has settled which course and which weekly slot, and the pricing page explains how pausing, missed lessons and a move between group and one-to-one work.

FAQ

## Essex questions

About the county, the pier railway project and how we teach.

### How many people live in Essex?

At the 2021 Census the twelve Essex districts plus Southend-on-Sea and Thurrock held 1,860,208 usual residents, from Office for National Statistics data on Nomis. Colchester was the largest council at 192,715 and Maldon the smallest at 66,208.

### What are the largest towns in Essex?

By ONS built-up area: Southend-on-Sea 182,305, Colchester 130,245, Basildon 115,955, Chelmsford 110,625 and Harlow 93,580. The page lists fifty-five Essex towns above five thousand residents.

### What is the pier railway project?

Learners use the pier's published timetable and speeds to work out how many trains the service needs, how that changes at higher frequencies, and where two trains on one track must pass. It is a model, not a description of how the railway is run.

### How long does the pier train take?

The pier is 1.33 miles long and its site gives train speeds of 8 to 10 miles an hour, so the running time is roughly 8 to 10 minutes each way before any slowing at the points.

### Why can a small speed change need an extra train?

Because fleet size is the round trip divided by the gap between trains, rounded up. At a ten-minute service, our model needs two trains at 10 miles an hour but three at 8, since the slower round trip just passes twenty minutes.

### When are Essex school holidays?

It depends on who runs the school: the county council, Southend-on-Sea or Thurrock, or an academy trust with its own dates. The county's term-dates page turned us away when we checked on 26 September 2026, so holiday pauses are arranged directly with you.

### Is there a classroom in Chelmsford, Colchester or Southend?

No. Every lesson is live online, so a learner in Burnham-on-Crouch joins the same class as one in Basildon without travelling.

### What ages do you teach?

Our youngest learners are six and our oldest sixty-seven. Scratch comes first for small children; around ten to twelve most switch to typing Python; secondary students and grown-ups branch into algorithms, data, AI and building software. Where anyone starts is decided in the free lesson.

### What does it cost?

Lesson one costs nothing. After it, a group seat is USD 100 a month and a private teacher USD 150 a month, paid month by month with no longer commitment.

### Do you help with the Essex 11 plus?

Maths preparation for the Essex and Southend tests is covered on two other pages. Here the subject is programming, and choosing or applying to schools is outside what we advise on.
