Yes, nothing wrong with that post/link, but it would have been even more useful if a description of the item was included, e.g. "a new trade magazine covering European Railways- requires subscription to view".
Please do post links to any material you find . I'm not sure wether it requires subsription or not is relevant really . i spose it could be frustraing to follow a link then find you cant go further , but by all means , please dont refrain from posting .
It is good to provide a brief description of what the link is about though , although i would have said the thread header describes it pretty well .
