While riding on a train of cars operated by the defendant, in April, 1905, plaintiff’s intestate Avas killed by reason of the derailment of the car in which he was sitting; the car after leaving the rails being overturned, and crushing the deceased underneath its weight.
Defendant Avas not a common carrier of either freight or passengers, and operated no passenger trains. It built and operated a short line of railroad from its logging camp and commissary at Woodbine to the Central of Georgia Bailroad at Ch’erbrook, from Avhich point to Sylacauga it used the C. of G. track. Its road Avas designed for its oaau use in its logging and lumber business; but a custom had arisen of alloAving its hands and employees to ride to and fro on its freight trains for their OAvn convenience, AAdiich Avas in time extended apparently to all persons Avho sought the privilege.
The deceased was employed or hired by defendant to cut ties on its lands at so much a tie, and at his discretion. Othenvise he had no relations Avith the defendant or its business. On the occasion of his death, he and *304a number of others had ridden up to Sylacauga, and were returning to Woodbine. The derailment occurred on defendant’s own track, and the train, consisting of an engine and a single box car pushed in front of it, was moving at a speed of three or four miles an hour. The grade of the road at this point had been constructed about a year before, and the track laid within four months. The grade had not been surfaced up, and a force of hands were then engaged in the work. The evidence is in conflict as to the condition of the track at or near the point of derailment. The plaintiff’s evidence tends to show that at or very near such point, which was on a curve, the outer rail sagged for a. space of four or five ties, and was thereby made lower than the inner rail; while defendant’s evidence.tended to show that the sagged space was for only one or two ties, and the outer rail was level with the inner rail.
The complaint is in 17 counts, and to each count numerous grounds of demurrer were interposed. These were sustained as to counts 3, 4, 5, 6, 7, 8, 9, 10, 11, and 12, leaving for issue counts 1, 2,13, 14, and 17. All of these counts predicate the right of recovery on the defendant’s breach to deceased while being carried as a passenger on •its train and counts 2, 13, and 14 are for wanton or in-ten iional wrong.
To these counts defendant pleaded the general issue, and special pleas 3, 4, and 5, which, in substance, assert deceased’ knowledge of the unsafe condition of the track for passengers, and that so knowing he voluntarily boarded the car and exposed himself to the danger, without invitation from or compensation to the defendant. Plaintiff’s demurrers to pleas 3 and 4 were overruled, and to plea 5 sustained. These various rulings on demurrers to complaint and pleas, with several rulings *305on testimony offered by plaintiff, make up the 45 assignments of error.
1. If counts 3 to 12, inclusive, had not been eliminated by demurrer, plaintiff could not possibly have recovered under any of them, since the evidence shows without dispute, and plaintiff’s counsel in argument assert, that there was no relationship of master and servant between deceased and the defendant. We are therefore unwilling to consider the theoretical merit of the first 10 assignments of error, because the errors, if any, were entirely harmless.
The 11th and 12th assignments, relating to counts 15 and 16, are not argued, and must be treated as waived.
2. To constitute one a “passenger” who is riding on a train, it is well settled that it is not necessary that the carrier should be a common carrier, nor that the train or car should be used or adapted primarily for carrying passengers. — Birmingham R., L. & P. Co. v. Adams, 146 Ala. 267, 272, 40 South. 385, 119 Am. St. Rep. 27. It is also well settled that the person transported is none the less a passenger because he pays nothing for his carriage, or because he rides for his own convenience solely, by the courtesy of, and absolutely without profit to, the carrier. — 5 A. & E. Ency. Law, 507; 1 Am. & Eng. Ann. Cas. 451, note; Indiana Traction Co. v. Klentschy, 167 Ind. 598, 79 N. E. 908, 10 Am. & Eng. Ann. Cas. 869; Harvey v. Deep River Logging Co. (1907) 49 Or. 583, 90 Pac. 501, 12 L. R. A. (N. S.) 131. The essential requirement seems to be only that the passenger is accepted as such — that is, for transportation by the carrier; the trust and confidence-thereby induced, on considerations of public policy, imposing upon the carrier the duty to reasonably safeguard, and not negligently injure, the person so carried. In some of its applications, this *306rule is undoubtedly a harsh one and the results sometimes seem scarcely consistent with reason and justice.
When, however, the passenger chooses to be transported on a train, not adapted to passenger service, such as a freight or a logging train, while he does not waive the carriers’ duty of due care with respect to his safety, he does waive all such precautions, whether in equipment or operation, which are inconsistent with the ordinary use and conduct of such a train, and cannot expect the carrier to change or adapt his service to the extraordinary requirements of a common carrier of passengers. In other words, he assumes the risk of injury from such accidents as are incident to such trains when equipped and operated in the usual way. — Southery Ry. Co. v. Crowder, 130 Ala. 256, 263, 30 South. 592; Harvey Deep River Logging Co., 49 Or. 583, 90 Pac. 501, 12 L. R. A. (N. S.) 131.
3. But, if the carrier is not a common carrier of passengers, and has not expressly contracted to carry in the particular case, a person entering upon its train and taking passage thereon might be, under various circumstances, either a passenger, a licensee, or a. trespasser. If his presence is without the knowledge and consent of any one in charge of the train, he is but a trespasser. If on the invitation, or with the knowledge and acquiescence, of such an agent, not authorized nor shared in by his principal — the carrier itself, or its alter ego — such person would be but a licensee. — McCauley v. Tenn. Co., 93 Ala. 360, 9 South. 611; Files v. Boston, etc., R. Co., 149 Mass. 204, 21 N. E. 311, 14 Am. St. Rep. 411. If on the invitation, express or implied, of the carrier or its alter ego manager, or of any authorized agent, such person would be a passenger. Id.; Harvey v. Deep River Logging Co. (1907) 49 Or. 583, 90 Pac. 501, 12 L. R. A. (N. S.) 131.
*307In the last instance he conld recover of the carrier for injuries suffered while a passenger, and proximately caused by the simple negligence of the carrier; while in either of the other instances he could recover under a proper complaint only for the wanton negligence or willful wrong of the carrier, including its failure to'exercise due care to avert injury after the danger was apparent.—McCauley v. Tenn. Co., 93 Ala. 356, 9 South. 611.
The complaint does not charge that the defendant was a common carrier, but only that it operated a train on a railway, and that the deceased was being carried by the defendant as its passenger. Pleas 3 and 4 are substantially alike; but plea 3 is, by formal averment, a plea of contributory negligence, while plea 4 is one of assumption of risk. Each plea charges that the deceased “voluntarily, of his own free will and accord, without invitation from the defendant, and without any compensation to the defendant, boarded the car on which he was riding,” and which by turning over on him produced his death.
Without regard to the sufficiency of the averments of the pleas to show that deceased had knowledge of the dangerous condition of the track over which he was riding, such as to import contributory negligence or assumption of risk in so riding, we are of the opinion that, if the quoted averments were true, they would constitute prima facie a complete defense to every count of the complaint based on simple negligence, and to such only are they pleaded. This is necessarily so, because one Avho enters and takes passage on the train of a carrier, not shoAvn to be a common carrier, without actually paying therefor, and without any invitation from the carrier to do so, is at best but a licensee, and not a passenger, and would in la.Av assume every risk of injury not due to the wanton negligence or willful Avrong of the carrier or its *308servants. If the complaint- showed the defendant to he a common carrier, the want of an invitation would he obviously immaterial, and the plea would be insufficient- as an answer to the liability charged.
It is to be noted that “invitation,” in the sense in which it is here used in these pleas, and as commonly used and defined by law writers in the connection, is a term of considerable breadth, and includes, not only express invitation, but the invitation that may be implied from custom, usage, or conduct on the part of the carrier, or its servants, if notorious or actually known to the carrier or its alter ego. — A. G. S. Ry. Co. v. Godfrey, 156 Ala. 202, 218, 47 South. 185, 130 Am. St. Rep. 76; Brown v. Scarboro, 97 Ala. 316, 322, 323, 12 South. 289. Upon this question of implied invitation, based on the known custom or usage of the defendant or its agents, much pertinent testimony was introduced on the trial, and this issue as made by the pleading was one of fact for the jury to determine.
Plaintiff’s witness, Boss Leonard, had testified that he was on the train at the time of the accident,'and at once examined the track at the point of derailment, finding a muddy place where two or three ties had sunk in the mud so as to be entirely covered, making the outer rail of the curve lower than the inner rail. The witness stated that “he had been working for defendant for more than five years last past.” Plaintiff asked the witness, “What caused that car to turn over?” Defendant objected on the ground that the answer would be irrelevant .and immaterial, and but the conclusion of .the witness, which objection was sustained by the court. The answer •sought wa.s plainly the witnesses’ conclusion as to a matter that involved expert knowledge at least of railroad tracks, if not of running trains. The witness showed no knowledge or experience that might have qualified *309him to answer such a question, since, for all that appears, his service with-the defendant lumber company may have been. restricted to chopping timber in the woods. The question was properly disallowed. • .
5. As part of the testimony of plaintiff’s witness-Chandler -(presented by written showing) to the effect-that the car was caused to turn over because of the lower-outside rail, and because, of the sagged place under the rail, was excluded on defendant’s motion, on the ground-that it was immaterial, irrelevant, arid, a conclusion of the witness. This witness was also present on the-train, when the accident occurred, and carefully examined the track; his testimony as to its condition being substantially the same as that of the witness Lennard. He stated that he was then in the service of defendant, and that he had had “several years’ experience in working as a section hand on railroads.”
While judicial knowledge may inform us of the general nature of the work and experience of a railroad section hand, we certainly cannot, discover in such a service any satisfactory assurance of expert knowledge of railroad tracks or their sufficiency for the accommodation of rolling stock, or ability to say that the condition of this track absolutely caused the overturning of this car while running at the rate of three or four miles an hour. And, if the witness was not an expert, and no expert knowledge was required for such a conclusion, manifestly his opinion could be of no service to the jury, since they were in possession of all the facts upon which his conclusion rested, and were equally capable of drawing a correct conclusion for themselves. 1 Greenl. on Ev. (16th Ed.) 549. The trial court did not err in excluding this testimony, and also the statements of the witness to the effect that the road at. this point was not properly constructed.
*3106. Whether or not the deceased knew of the dangerous condition of defendant’s road was, of course, a relevant inquiry under the pleadings; but the witness could not testify that deceased did not know of it — a rule of evidence many times declared by this court. — Bailey v. State, 107 Ala. 151, 18 South. 234; W. P. Coal Co. v. Andrews, 150 Ala. 368, 43 South. 348; Layton v. Campbell, 155 Ala. 230, 46 South. 775, 130 Am. St. Rep. 17. The statement was properly excluded.
7. The giving of the several charges set out in the record is not presented for review by any assignment of error, and we are therefore unable to consider any of them.
The record disclosing no error prejudicial to appellant, the judgment of the circuit court must be affirmed.
Affirmed.
