"In those days, I used to pull slip coaches; coaches which could be uncoupled without even stopping! That way, we always ran on time and there were never any delays."
— Duck, Duck and the Slip Coaches, eighteenth season


Slip Coaches
  • Class: GWR Slip Coach
  • Builder: GWR Swindon Works
  • Built: 1914

Slip Coaches are Great Western bogie coaches, which can be uncoupled at stations without the engine stopping.

Duck has three slip coaches, two male coaches and one female coach. It is currently unknown whether or not the coaches have any proper names, but Duck has given them the collective nickname of "Slippies".


Before coming to Sodor, Duck used to pull three slip coaches on "The Sunshine Line", part of the Great Western Railway. Later, Duck told the other engines about his coaches. James told the Fat Controller about purchasing slip coaches, claiming Duck's idea as his own, when the Fat Controller was concerned about passengers getting to their destinations on time during the peak summer months. James was rewarded with the chance to pull the coaches on Duck's Branch Line, but did not know how to time the uncoupling correctly. At Bluff's Cove, after uncoupling the rear coach, he slowed down to show off his paintwork. Because the last coach was still moving, it bumped into the back of the rest of the train. The slip coaches then refused to move, as James didn't know how to use them. 

Since Duck knew how to handle the slip coaches, he was soon put in charge of pulling them round the island. By coincidence, the Slip Coaches that the Fat Controller purchased were the same Slip Coaches Duck used to pull on the Great Western Railway and they were glad to see their old engine.

At Christmas, when Connor needed extra coaches for his last train on Christmas Eve, the slip coaches offered to help. The third was released at Kellsthorpe Road, the second coach was released at Maron, and the first coach was released at Wellsworth. Unfortunately, the first coach overshot the platform, but Thomas managed to shunt the coach to the platform.


The Slip Coaches are very good friends with Duck. Like most coaches, they do not like being bumped by an engine. They can be very judgemental if they are not treated right, and need to be handled delicately.


The Slip Coaches are based on the Great Western Railway's Slip Coaches. These coaches had the unique ability in which they could be uncoupled at stations without stopping. The uncoupled coaches are stopped when the guard sets a handbrake.


The Slip Coaches are painted maroon and cream.
