Hello Martin,
Laurence, (Tri-angman) here - yes same issue. I have 7 new and unopened Rail Express Limited Edition ones for sale on my web site and on checking 6 have minor through to major cracking issues on both sides of the spine. I have reported the issue to Dapol with photo`s and am just awaiting a reply - will let you know the outcome. As an aside I have the `Trainlines of Derby` brown versions and all are perfect
