My model

the model

When the Mersey Railway was electrified some of their locos were sold to the ADR and they proved very suitable for the coal traffic that had previously been worked by the Taff Vale Railway. These locos are not often seen modelled, so became rather irresistable. My model was based on drawings of the Mersey locos published in various periodicals, information in the RCTS Locomotives of the GWR Part Ten and a trip to Liverpool (see below) - it was only after I'd finished it that a general arrangement drawing became available from the HMRS!

 

the model

The body was made as separate units that bolt together: this was not done carefully enough and some joints do not fit as well as they should. It was quite a challenge to decide where the units should separate. For example the cylinder ends extend into slots in the inside frames so the cylinder block can't be lifted out with the smokebox.

 

the model

The chassis has double frames with the bearings in the outer frame, suspension is by continuous springy beam over the drivers and a simple coil spring round the bogie pivot.

Having the model bearings in the inside frames and having the outside ones part of the body would not work because the driving wheel springs are underhung. If the inside frames were made part of the body, so removing the problem with the cylinder block, there would be a problem of frame stretchers...

As there are a few problems with the model I aim to build a second version (with belpaire firebox) based on the more accurate information I now have. Has anyone some brilliant ideas of how to split the body units? After that hopefully will come a couple of the 2-6-2Ts.

 

Cecil Raikes

In 2013, as part part of my research I visited the workshop of the National Museum in Liverpool where Dale Riley was very helpful in facilitating photography of "Cecil Raikes". I've included here the photos I took that may be of help to modellers, some being views not often photographed. Below the small images is a table of observations I made during the visit.

Larger versions of the photos can be downloaded by clicking on the small ones.
