The Talyllyn Railway's Hughes 0-4-2ST No. 3 "Sir Haydn" (originally Corris Railway No. 3) will visit the Corris Railway soon after Easter and be available for service until 17 May 2012.
 
It will then be out of ticket, but stay at its old line on static display at Maespoeth through the summer.
 
The aim is to boost interest in the Corris Railway's project to construct a near-replica of it, which will become Corris No. 10.
 
The visit encompasses the 5-7 May 2012 Corris Steam Gala, when TR No. 3 will run with Corris No. 7 (itself a near-replica of TR No. 4 Edward Thomas, which was originally Corris No. 4).
 
The significant point is that this is the first time two steam-hauled trains have run on the Corris in preservation.
 
The gala will also feature double-heading and demonstration works trains, with No. 3 also likely to be in steam over 12-13 May 2012.
 
The loco now known as Talyllyn Railway No. 3 "Sir Haydn" was built in 1878 for the original Corris Railway, becoming that line's No. 3.
 
The Corris closed in 1948 and the loco (with Corris No. 4) were purchased in 1951 to assist the preservation of the Talyllyn Railway, the pair becoming TR numbers 3 and 4, both later being named for the first time.
 
No. 3 has previously made a guest appearance at Corris, in 2003.
 
The latest visit reciprocates the appearance of the Corris Railway's new-build 0-4-2ST No. 7 to the Talyllyn last October.
 
Guest loco appearances for both railways are limited, the Talyllyn and Corris being the only surviving 2 foot 3 inch gauge lines in the country.
