The first of Northern's fleet of 102 Pacer trains have been taken off the rail network, the operator has said.
The outdated trains, many of which have been running for 35 years, were due to be taken out of use by 2020.
But, with just a few weeks of the year left, only three trains have been retired.
The much-maligned trains will continue to be retired and then scrapped over the coming months, with "a handful" remaining.
Northern, which covers the North West, North East, Midlands and Yorkshire, has said 101 brand new trains will join their fleet as part of a £600m investment.

Trains on the West Coast Main Line, including those for Virgin West Coast, Northern and TransPennine Express are starting to run again after repairs were completed to hundreds of yards of overhead cables that fell down yesterday.
Network Rail engineers who worked through the night said at around 07:00 this morning that everything was now fixed.
But train operating companies say it will take some time to get services back into order if they run between Preston and Oxenholme, and services to Barrow and Windermere are also affected.
A Network Rail spokesman has apologised to passengers affected by the lengthy and ongoing closure of the West Coast Main Line between Preston and Lancaster.
This section of the West Coast main line will be closed for the rest of the day while we fix a quarter of a mile of damaged overhead power lines. Investigations are under way to find out exactly how the cables were brought down but our immediate focus is to fix the cables in time for start of service tomorrow.
We’ve been working closely with train operators to recover stranded trains today. Passengers are being advised by some operators not to travel this evening and tickets will be valid tomorrow.
The train company Northern says 33 of the 101 new trains being brought into service are now operational.
Stations served by the new fleet include Oxenholme and Barrow and Windermere.
Earlier this week, new statistics showed fewer than half of Northern's services ran precisely to time, down on the summer figure of 61%, although the company blamed bad weather and congestion on rail tracks.
Northern has issued a "do not travel" warning to rail passengers on three routes as flooding continues to cause severe disruption to travel.
Flooding at Walsden has blocked the line between Manchester Victoria and Leeds and Northern advises customers not to travel at all between Hebden Bridge and Manchester Victoria as the roads are also closed.
Passengers are also being told not to travel between Sheffield and Gainsborough and Sheffield and Lincoln.
There are no services between St Annes and Blackpool South due to flooding in South Shore Blackpool but rail replacement coaches are operating between the two stations, Northern said.
Flooding at Culcheth Farm had blocked the line between Eccles and Earlestown but Northern say services are now able to run at reduced speed on the line between Liverpool and Manchester Victoria. However, it says delays are likely.
Flooding between Liverpool Lime Street and Manchester Victoria is disrupting rail services.
National Rail Enquiries says trains will be delayed by up to 15 minutes, cancelled or revised.
Services are expected to be hit until 15:00. Customers are advised to take the next available service, and TransPennine Express tickets will be accepted by Northern.
