The poem is by far the most famous ever written by McGonagall, and is still widely quoted. It begins:
"Beautiful railway bridge of the silv'ry Tay
Alas! I am very sorry to say
That ninety lives have been taken away
On the last sabbath day of 1879
Which will be remember'd for a very long time."
And it ends:
"Oh! Ill-fated bridge of the silv'ry Tay,
I now must conclude my lay
By telling the world fearlessly without the least dismay,
That your central girders would not have given way,
At least many sensible men do say,
Had they been supported on each side with buttresses
At least many sensible men confesses,
For the stronger we our houses do build,
The less chance we have of being killed."
